I think you have to find solace in place you find joy and happiness. Even if it’s just going to the park and seeing people walk around. I know it’s not the same as being around people but I feel you. Growing up I never kept many friends and I when I really needed someone to talk too I didn’t have anyone to turn too, no lifetime friends. Even now at work, I don’t keep many friends just colleagues that I talk too at work and nothing more. I do and don’t regret not expanding my horizons, I do because obv I could’ve had someone to talk to when I need too and be around. I don’t because sometimes I realise that lots of people I thought could’ve been friends probs weren’t good friends, they would take more from me than I would give. So yeah.
I hope it gets better.
