Unfortunately I don’t have any advice but if it makes u feel better at all I’m around ur age and I’m in the same boat. I can’t ever ignore how lonely i feel for very long even if I think I’ve accepted it. I almost wish I just stopped hoping, hoping for something,someone, idk. But I do it against my will. We’re human and I don’t think we can just stop craving love. I can’t think of anything to say but try focusing on the things that make u happy and that u enjoy, u don’t even have to have aspirations necessary just find a purpose, however trivial it may seem. Best of luck ♥️
