I didn't had any friends and have been socially isolated for most of my life.
I never had a girlfriend.
I went several years in college, and never had a single friend nor a buddy, I was NEVER ever invited to any parties, and if they went out for a beer it was with the whole group or class which I only followed (less than 10 times).
Though, I have been constantly ostracized by all of them, and often bullied and threaten.
Those years were a nightmare.
The only sympathy I could get was from some lecturers and professors, though they weren't my friends, in term people you hang out with.
I was never wished happy birthday or received a gift from someone outside of my family, the day of my birthday.
I used to hang out with a few people, but it was very short, since I realized that I always contacted them one-way, or they were pushing me down.
I had a buddy for a few month, he was often not available when I invited him, but we did hang out together one or two time a month, went to some parties, clubs, events. He was constantly into girls, probably a chad-lite. It ended very badly.
Actually, he was the only one to regularly hang out with me and to invite me for the last couple of years.
Now, I literally only have my parents, I'm friendless.
