How can I rebuild my low self esteem?

I'm a 17year old female and my self esteem is crippling. I have no confidence in myself. I'm trapped in this empty void and I'm hoping my combo of antidepressants can help. It'll take a few weeks though. Sorry I went off topic, I guess what I really need is a friend, or something to check in with every once in awhile. My Kik is manga 1094
