I cry so much lately

I’m 22. All of my friends live hundreds of miles or more away from me. I can’t even get someone I match with on an app to begin a conversation with me. I don’t understand why I don’t seem to be allowed to have anyone who cares about me in my life. I’m so touch starved - even hearing about other people having things like relationships or sex make me sad and jealous and I hate it. I hate feeling like this. I don’t know what to do anymore.
