Is there anything I can do to stop feeling so lonely all the time?

I've never been in a relationship before and it's getting to the point now where I'm constantly breaking down crying nearly every night because I don't have anyone special like that in my life. I just wanna know what that kind of love feels like and it kills me inside. These feelings keep getting worse and I wish I could feel better about it, but I just can't. I just don't know what to do anymore. I just want that special someone so badly I can't take it anymore and I'm desperate. It's all my mind thinks about and any mention of someone else's relationship makes me insanely sad because I feel so alone. I don't know what to say anymore...
