Got 3 amigos and am happy

I'm really not the talkative type, I observe first and then try to match up my words. I tried to catch up to one person through my whole school life, she was an amazing person. I really wanted to talk to her and be her bff. We had a group of 3(she, I and another friend), as an introvert I was basically left out. As we went to college, she kind of drifted out from me, she left me out and would hang with other people. All I could see was a long empty bench with just me at one side, so my condition got worse and I started to have panick attacks, I would stress out a lot, it became hard for me to bond with other people. And as time went, I enrolled in another university. It was hard at first, I walked and sat with three people who I used to see in my college, then slowly I began to open up with them, I started laughing and began to make more friends, those 3 years that I spent with them are my precious memories. I would behave like a spoiled brat and they would just laugh out. It was so much fun, due to covid we cannot meet up but we chat a lot. Somewhere in my 2nd year, my school friend came up to me, she told me how the university life wasn't getting fun and she was alone, so I basically ditched my uni and went to look out for her, we started talking again but I didn't talked much with her, whenever we went out it was difficult for me to cope with her, as days went by she got angry as to why I don't chat with her and why she was the one to chat up first and said to fuck myself, so I said ok and didn't text. So we don't talk at all now but I'm kind of glad, I've got some friends who accept me as I'm and I'm happy.
