I Don't Know What To Think

Hey friends. I have major depression, I've been seeing a psychiatrist and a therapist for a while but I'm not getting better. I'm a senior in high school and I've never had a boyfriend, just "things", that never end well. One of my fears is that I am going to be alone for the rest of my life. I want love, I want someone to love me and make me happy. But I feel like that won't ever happen. And it really, really sucks. Everyone around me is getting with someone or is happy with someone, but I'm alone. Will it always be like this?
