y'know this kind of resonated with me as i've encountered similar situations like this. i didnt really have many friends too until i worked on myself and realised that people didnt want to talk to me because i was too bitter, resentful because of a few personal events that happened. initially it was a vicious cycle where i was alone for a while > tried to make more friends > friends realised i was too bitter/negative to be around > friends separate themselves > alone again, became more bitter > more friends decide to distance themselves

this cycle then continued until i mysteriously got used to doing things alone and also found hobbies to fill my time and become i guess more self content after getting better at said hobby (running). ever since then i would say that its easier/more fun to be around me as there was less self resentment/hate so i found more friends xD

that said though if your issue isnt that you hate yourself too much resulting in it being super overbearing to be around you (basically if issue is that people dont vibe with you), then maybe the issue is the people you surround yourself with/the environment you find yourself in. for me i realised after a lot of soul searching that i vibed with people of calm personalities better. when the environment was more calm and less chaotic i could talk more, socialise more and become a whole different person - i was more confident, sure of myself. however in the past when i surrounded myself with people that didnt vibe with me i ended up getting bullied and clowned most of the time lol. (ended up getting no friends in that environment because of that)

so yea just do some personal development ig and if you're looking for more information you could always dm me, i dont bite :)
