I'm reposting something I wrote a few weeks ago because it explains what I'm looking for best:

This might be a weird request, but I'm looking to be someone's main support system, friend or whatever else. When I talk to people I always get the sense that I'm just there until they meet someone better and move on. I've had this happen to me multiple times, and I just want/need one friend I can be my true self with, give it everything I've got and feel like that's enough. I get a lot of anxiety and some depression, so I'd preferably like someone who at least knows how that feels.

I'm horrible at pitching myself. I'm terrible at small talk but I thrive with deep, meaningful conversations. I'm naturally inquisitive and caring sometimes to a fault. I'm one of he least judgmental people you will ever meet and I have a lot of patience. I'm looking for someone who is willing to give me the same.

Age, gender or whatever doesn't bother me. I tend to get along with people younger than me though. I don't relate to anyone that's my age, as I don't have a job, girlfriend/boyfriend or my college degree yet and I feel kind of lost. Everyone around me is either in a long term relationship or starting their career and I feel somewhat left behind. For that reason also I'd prefer if you're single. I don't want to just be a distraction while the person you'd really want to talk to isn't around.

This was just a huge ramble, sorry. Thank you to anyone who got through all that, and I hope to hear from someone soon :)
