Hi people, I am 22(m) and I'll spare you some time by not talking about who I am or the details of my life. 

I currently have no friends.(I am introverted in nature and have always had problems with making and keeping friends) I dropped out of college after graduating highschool. I was clinically depressed after a hospital incident when I turned 16. Right now all I do is play video games in my Parent's house(I am unemployed.) The only emotional anchors I have right now are my parents and my older brother. I'm barely holding on to my sanity as is. I've already had some unreported mental breakdowns in the past years. Now I'm worried about what will happen to me after my parents inevitably pass away and my brother moves out on his own. What will I do? I'm still in the middle of career-exploring and am not doing too well. I barely have motivation to take the steps in my current career goal. I get this feeling that it will be so much worse for me in the future because as it stands....it seems like I have no future. I believe I am doomed. Can someone relate to me in any way and reassure me that it will be okay? I can't see any of this ending well.
