how do you deal with feeling alone and unloved

Every time I find someone and let them in it’s like they don’t feel the same way that I do about them

All I want to do is talk to them everyday and see them every now and then but that seems too much to ask of them

I feel like maybe I’m not meant to be loved

I’m almost 21 and have yet to find someone, a best friend, a partner or whomever that loves me the way that I have loved them
