"something clicked and my depression..." -> trigger "but after..." -> 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"
