I'm depressed and I just don't know what to do from here
Well could you tell me what you would do if you weren't depressed?
If I were not depressed I would go running but I cannot do that now.
It is important that you get yourself feeling better. It is important to get help when you are depressed. If you do not it could get worse for you.
I feel like I should be excluded from society. I don't want to talk to anyone.
Well going running wouldn't require you to be around anyone and you may feel better if you do something that you love. If that doesn't work, then you could always seek a psychiatrist for help.
