Is it normal not to want to leave my home?

I suggest taking a trip to your doctor because drinking isn't going to help, it's a depressant in itself and will only make you feel worse.

I think you should go to your doctor and tell him/her how you've been feeling and that you don't have much desire to socialize/go out the house/have sex.

Because it sounds like you've relapsed into depression again. I know, it's not nice but going to the doctor will help.

And why exactly are off your meds? It sounds like you are worse than ever. I'm not a big fan of using meds to solve one's problems and sincerely believe that one always has a choice in how they deal with things like depression, but from what you've posted, perhaps in your case, you might want to get back on the meds.
It seems so fatalistic when I read; "Im fine alone and enjoy my alone time", and honestly I don't believe it for a second, or why would you be posting on IIN?
If you seriously want to break this cycle, then you are going to have to force yourself to do it. Go out and do things, not necessarily drinking, but go to the zoo, volunteer at an animal or homeless shelter, go to the races; something, ANYTHING, other than sitting in your house thinking that you are OK like that.
Choose to live your life and don't give in to the depression. It can be done, I know.

People's interests and personalities change. It does sound like you may be suffering from social anxiety and depression, but I would personally step out to say that neither medication nor alcohol will cure this.
A good step would be to get a therapist. I don't recommend psychiatrists usually, merely due to the fact that many are too hasty to hand out medication. If you can find a cognitive behavioral therapist in your area, that would be my first recommendation.
Another step would be to get involved with something spiritual. I don't necessarily mean going to chuch (or any other place of organized religion for that matter). Pick up a Bible, Quran, Tohah, Bhagavad Gita (or a copy of the Vedas), or the Pali Canon (or any Buddhist sutras), etc. Most of these can be found free online, used book stores, or regular book stores.
The next step: Take a walk. Take a bike ride. Take a swim. Drive around. Lift some weights. Jump some rope. Whatever you choose, get up and move. You won't feel like it, I know. You won't want to do it, I know. Do it anyway. Start small, and work bigger. You need it. I promise. Exercise releases endorphins, which make you feel good, which allows you to get on the track of becoming healthier.
Take a minute to meditate. Breathe in deep. Acknowledge that breath in. Breathe out deep. Acknowledge that breath out. Take a moment to think about right here. Right now. Not ten minutes ago. Not yesterday. Not a year ago. Not what you have to do later. Now what you have to do tomorrow. Or in a week. Take a moment to be right here, right now. Ask yourself, "In this very moment, is there anyone hurting me?" Give yourself a chance to relax, and enjoy one moment. If you can enjoy one breath, then you can enjoy two. Then so on and so forth.

Mind + Body + Spirit = Health

Best wishes!

These are all classic signs of major depression and social anxiety disorder I suggest seeing a psychiatrist.

I don't want to leave my house either, but part of that is because I'm ugly and unemployed right now. Maybe when you're feeling successful the confidence will come back.

Thanks to the people who care and want to give great advice! The negative peeps well they have their own issues,to be so nasty and lash out and all. I will pray for them.Give what you get they say but so peeps just don't get it or give. Try a little love and kindness

Why doesn't your roommate/boyfriend help you?
