"something clicked and my depression..."
-> moping & self-pity
" It just upset me...I've never had that..."
-> observational bias, you very well likely have
"Like I was the only one wanting a real friend"
-> but weren't acting like one; it's a giving act, not an exchange
" pissed off mood...I am a good friend"
-> then use this determination to go and be a great wavemaker in the world around you
"I would want to hang out, but they were always busy, and when I would see them, EVERY SINGLE TIME they would want me to fix their pc, or help them with something"
" I do things without expecting anything in return"
