I used to fret over this all the time. Especially with people who I think should love me. You can't make people love you. It sucks, I know. I used to feel unloveable. I don't know when really when those feelings of mine changed. Maybe I got used to it and it doesn't bother me anymore. People usually disappoint me anyway. I try to live my life now as not to expect anything from anyone. I'm not being much help here for you, sorry. Just be yourself. You have to be happy with your own company before love finds it way to you.
The best way to get love is to give love.
