I have borderline personality disorder (BPD) and avoidant personality disorder (AvPD).
One of the worst things about it is that I often think: "I need to talk to someone so bad, I can't live like this for my entire life..." and after barely 10 minutes I could be like "Nah, the only problem here is mankind, and that's why I don't talk to anyone and don't have any relationship, they don't deserve me, and I'm fine with it.".
Basically I spend my days at the computer, talking to my parents only, and leaving my house just to take my dog out or for some commissions, and I'm often depressed, thinking about suicide.
My computers are the only reason I'm still here: my wish for learning is superior to everything.
