Is it normal i'm becoming a stereotypical nerd?

I know what you mean.
The main problem is self-disciplin. I know cause I don't have any.
But some of your problems can be solved in a nerdy enough way.

Like the healthy food thing:
Start surfing the internet to learn about food, fat, sugar, protein, vitamins and stuff. Become the smartass that knows all about that shit. The guy that reads the ingrediants and knows exactly what they mean. This way you can turn shopping for food into a game where you have to find items that are actually healthy and don't just pretend to be. A real challenge for a real nerd.

The other thing is the "working out":
I used to have a gym membership, but packing my stuff, going there, change, work out and having to see all the buff dudes there, made it really hard to motivate myself.
Now, I do the lazy version: I bought some good weights and some other tools. Now I can work out whenever I'm bored, which is a lot. I's not hard, I don't have to go anywhere and nobody sees, hears or smells me. Hell, you don't even have to buy anything, you can also just do push-ups, sit-ups and stuff.

You can also make other challanges for yourself, like: "I'm going to see how long I can last without the internet" or: "Today I'm going to take a walk somewhere I've never been."

First off let me just say that I think it's great that you have some amazing friends and you cherish them. Seriously I see a lot of posts on here about people who have a hard time making friends. Also so you sound like a cool dude based on what you said about yourself. I mean there are a lot of people who can spend all day on the internet and I hope you find them.

As for becoming a stereotype, I think you know the answer. Work out, eat healthy, buy some acne cream. I get that food is great, believe me I do, but you have to manage what's important to you. Do you care enough to actually make a change? It doesn't even have to be drastic, just try going for a walk once a day. Also eat more healthy foods, try making some stuff at home. Again I get the struggle, but you'd be surprised how a little effort can go a long way. And how delicious home made food can be and how easy. Personally I use to eat fast food almost every day, but recently I got a gym membership and I haven't had a cheeseburger in about a month. Fast food isn't difficult to give up, so long as you're aware that it's a problem and don't mind working out. You can do it, I know you can. We've all been where you've been, at least I'd like to believe so. But it's up to you to pick yourself up and try to make a change.

I just read the post telling him to "grow some balls". Once again this is how poorly understood depression is and how there is such a stigma attached to mental illness. You are shaming him for being ill! Shame on you!

I can't believe that everybody is missing the obvious! This young man is suffering from clinical depression and should seek psychiatric help! He knows what he needs to do, get out more, make new friends, eat healthier and exercise, but he can't because his brain chemicals won't let him! People aren't understanding that sometimes you can't just make yourself do something no matter how much you want it. At the very least he should be evaluated by mental health professionals. Perhaps he would benefit from an anti-depressant, but I personally think he should try counseling first. Learning Cognitive Behavioral Therapy from a therapist could do wonders. This man isn't lazy or lacking in motivation. He shouldn't be blamed for not trying hard enough. A combination of therapy and wellbutrin have helped me immensely. This man should seek help so he can find a plan that is going to work best for him.

Thanks guys and gals - you're all really helpful

heres my advice, sell your computer, get off your ass and do a bit of running, get a hobby, be careful on what you eat, grow some balls!!!

I am becoming that way too. It is because most of the people I meet now are just trying to get something. Not really interested in being my friend.

Go outside more. Get a girlfriend. Look forward and put up goals. Chase those goals, reach those goals and set new ones!

That way you will be a normal guy. Cause browsing shit on the internet and watching movies is cool an all, but it's not important. A real life is a lot more important. I'd rather go out for a drink with my mates, than sit at home in front of a damn computer.

Also pick up a new hobby. I turned my car into a hobby. Make it shine. Improve bits on it. I try to build an RC boat with a diesel engine. So far I got the hull, the controls and some of the engine parts and I'm still working on how to mount the engine and how to propell it (propeller, or jet thrust). Even cooking can be a hobby. It's actually very relaxing and very rewarding to cook a good and healthy meal. In my situation it's a must, cause my girlfriend can only burn stuff in the kitchen XD

Becoming more social isn't too difficult if you have the confidence to try it. Try to get confidence from your current great friends - if you can be friends with them, why can't you be friends with anyone? - and apply that to other people. It doesn't matter if any conversation you try to make sounds rehearsed or unimpressive to you - small talk is enough. You'll find that you only sound weird to yourself, and to other people you sound normal and friendly. Other people like being talked to if they seem bored, and if you talk to them they generally respond with pleasant surprise that you bothered.

If you can become more confident by socialising, you'll realise that that's all you need to be happy and your other problems are secondary and you can work on them later. I strongly believe that the socialising one is by far the most important to set right.
