How was I supposed to handle this social situation?

Basically, I am going to go back in time to 2 yrs ago. When I first started med school. I was in a class of 35 students so relatively small class. However, I didnt fit in. It became apparently by the first week.

I tried to be social such as introducing myself to others and sitting next to others in the cafe. I noticed that my friendless was met with neutral energy. By the end of the first week, everyone had figure out the people they wanted to be friends with. I knew that something was off when I went to the first bar event. Everyone had car pooled except me and people had formed social circles. I will admit that I am not the best conversalists but I wasnt given a fair opportunity. Most people would stop talking to me within one minute if I was not engaging enough.

I tried to not take it personally, but I was iced out at the next social event. No one expecting me to come. At this point trying to talk to women in the class was pointless. It was clear I was unpopular and most of the women didnt even try to hold a convo except my future female friend. She ironically was the prettiest girl and she took me under her wing. She friended me first on instagram. She even told me that you dont have to sit alone.

Till this day, Idk if she ever liked me. I say this because in the beginning she was extremely touchy and teased me alot. She clam down once she got a bf. But it was crazy becuase I asked her to let me take her to the bar. She agreed and even brought me a cookie as thanks. At the bar, she made it clear that I took her and I was taking her home. I screwed up back then being shy so she went home with another dude lol. That is why I say she might had a small crush. We only stayed friends because she actively text me even presently. But back to the story.

I had it tough. I even tried to become more social by talking more. People just made fun of me. Alot of the guys would hang with my female friend and block opportunities for me to connect. Like inviting her to their house and a couple others. I tried therapy, social skill training, and life coaching. At first I was gaslit into thinking I was the problem. However, at they heard me complain about how people typically never talk to me first unless I walk up to them. They told me to just move on. My last ditch effort was to get drunk with them since I am actually the life of the party. They recording me drinking and claim I was an alcoholic. And that I love driving home drunk.

There was no people on the outside unfortunately. All I had was coffee shops and hobbies. Eventually I isolated myself and moved on. Now 2 years today, I dont even talk to any of them except my female friend. I have a soft side for her since she was supportive back then.

But was there a better way to handle this? It significantly added to the reason why I think everyone is fake and I dont like to socialize as much anymore.
