it sounds like you're feeling lonely despite having irl socializing? do you feel lonely all the time or just when you're alone or just certain times/late at night?
my loneliness is p much due to not having anyone in my life irl, so idk if the things I find helpful will be helpful for you but my pet helps me a lot. that's a big responsibility though so might not be the best idea if you're not planning on sticking around. I had to leave fb bc it was making me feel left out and lonely big time. I've been socializing here instead bc ppl don't just ignore me, plus it's strangers so if they did ignore me, it wouldn't hurt my feelings lolsob. Therapy helps me, I feel like I'm free to vent about things that overwhelm the few friends who still occasionally talk to me. I do have to be careful what I tell a therapist though.
And I've been doing rituals lately to contact my ancestors, talking to them and getting help with decisions. I can tell them anything so in some ways it's better than therapy for me. if this is something that appeals to you (or anyone reading) and you have anyone close to you who has passed, a candle and something that makes you feel close to them, a picture, an item that used to belong to them, their ashes, etc. will do. Anything you associate with them. I suggest having additional things like their favorite music, tv show, food, flower, or scent in the environment if you can as well. Focus on them while you light the candle and continue to focus on them and just talk. The first time I did it, it felt a little silly and I didn't know what to say but things were really bad for me. All I said was "I need help" and I just sat there quietly feeling their presence. a week later I got something in the mail that was incredibly helpful and has kept me holding on to hope ever since. I can't promise that will be anyone else's experience. I really didn't go into it hoping to receive anything other than their company. Since then I've been able to open up a lot more and not feel so silly talking to them.
I hope you find something that helps you feel less alone <3
