My last 2 years of downfall also happened after highschool after the rug was pulled from under me. I can relate to loosing everything, friends, what amount of social status you had amongst people you knew. I feel like the years between highschool and in college are never talked about and if they are they're always referred to as the best years of your life when imo they're really not. Not the best years by far. The stress of wandering and falling is apart of this period of life. Its a double edged sword. Its sucks to have nothing but its also a point where you can start something new. I'm not out of this transitional part yet so i dont know how i can help but i found that letting go and just trying anything of interest will sometimes lead to something. If i find that it didnt work out or i didnt make any friends i try something else that catches my eye. It will definitely take alot of time so go at your own pace. Try not to stress about making something of yourself immediately or in the time that everyone else does. You just do you.

Sorry if this sounded like hippy dippy shit but its something im trying myself at the moment after i was given less than helpful advice. Feel free to pm me.
