Ive felt like that too. No friends, and like Im going nowhere. If it makes you feel better, Im 28 and moved into my parents basement a few monthes ago.
You have a LOT going for you. You are 50 days sober.....that is fantastic! Now it seems you need a plan to find some wholesome, sober friends (they DO exist, even in a young age group) and find the way that works for you to overcome your negative feelings right now.
You can do it!
