Is it normal to be in this slump

So I'm aging and going through the ropes of such at 23 yo. Past story is as follows. Childhood was filled with mostly hanging out with a couple of friends always having fun as a child does but yet in school my social fear was fairly visible. I did receive a minimum amount of "bullying" for my height and teeth mostly. It wasn't anything major, mostly just kids reminding me of my flaws. As a kid it seemed like my family was just more active in taking trips and seeing other family, in general there was just more family activity. Then comes highshool where I met the friends I still talk to today, the first two years where average I'd say. We got into parkour for a bit then into disc then music. That's another thing about me and the people I associate with, we always looked for something to learn and get good at but there's too many minor details to drag into this here. Either way, at this point it seemed like I was never home which was a major change from me being always home. Then came the last two years of highschool, welcome to the stage; drugs. We tried just about anything that wasnt critically dangerous I'd say the worse healthwise being triple c's and spice (k2). And worse mental wise being lsd. We wouldn't do the harder drugs often at all, it was mostly just weed. Either way it'd be me and a group up to 8 or so guys almost everynight meeting up in a garage and getting high, it was a great time for everyone. In the midst I did have my one and only girlfriend for around about 2 years. That ended with her just leaving saying I'd changed and was emotionally abusive, which I can see. I'm a very joking person and sometimes what I say doesn't translate very well with others. Trying to keep it short here and skipping many details, here I am now. Most of my friends have had kids or have moved (just like you'd expect) I got one that's still fairly steady and a few more just coming back into the picture. We all still smoke weed and I've since broken my intoxication for a year after some health issues and have returned to smoking roughly once a day. I feel empty, I feel like there is nothing more for me to experience and the things I do want to do cost more money and dedication than I have. I fear I'm letting the last 5 good youthful years of my life go to waste even though I know how to take advantage of it. My downfall is my social awkwardness. I fear that it'll lead me to be that 40, 50 year old guy with a dead end job, a shitty apartment, no family, no friends, detached and hating myself for allowing it to happen. All that being said I just cannot break out of the slump. I'm back to being inside 90% of the time, the few times I do hangout with anyone we're just blazing and talking, not doing anything proactive. Scheming for a better life but never acting out. Its extremely hard for me to talk to someone unless I know how their brain works so meeting new people is the biggest pain in the assignment because I never get to the point of actually knowing them. Most conversations with new people are short and direct. I no longer want to be open about my feelings because I've read and read and read for the past 5 years and when it comes to personal emotions it's just a lost cause trying to relate anymore. Everything I feel has been written out a million times with solutions to everything but it's easier said than done. I've become almost completely detached from my family and in fact very irritable anytime they want to talk and I absolutely despise that fact. Of course I fear being alone the most as that's already what it's come to. Most of the time it's just me and my thoughts and I believe they are slowly poisoning me. The only other step I have to take to become fully isolated is to move out. If it weren't for my family ambiently existing in the same house I'd already be isolated. The most interaction I get is at work where again, it's mostly short and direct unless I'm talking to the couple of people I see everyday. Aside from being alone I fear scratching the surface of insanity and never coming back. With all the drugs and thoughts it's not hard to see myself drowning in my own personal beliefs. Now this is a very short explanation of what I'm experiencing and I just want to know if it's truly as normal as people say it is. Through the ours of reading Internet vomit my understanding is this is just how it is for this age group. My other question is if it'll actually smooth itself out closer to my 30s. I also understand the extremes can go in either direction Im just curious if anyone else has a success story after going through such a bout of foolishness. And lastly, how can I take advantage of my traveling and experiencing years if I've got no one else to take the risk with, and with minimal income? I know I shouldn't rely on others but I don't think I can allow myself to go it alone and I know with a certainty I won't be making new friends with any amount of ease.
