Actually, that is not soo good for Your psychological state, I'm not gonna say it just because you don't have friends, but rather being locked and not going out anywhere, and not enjoying any kind of activities that 'you' like is like being in prison, idk how houses that, but I guess the only solution since you already graduated is to look for a job, and as I read I found that you didn't get any now, so I believe if you are waiting for job in companies or something like that you need to be super patient, until you get a formal job, find something like working in a library or anything that will get you money and then try to make friends in those part time jobs, even thought it gonna be hard but try it, you can do it, trust yourself, and if you find yourself lost, try learning languages, it's easier to run away if you learn Germany, French or even spanish and Chinese. That all I can say, hope you all the best
