Ask your parents if they can help you to find a good therapist for depression. Just keep in mind, best results are not only meds, therapy should be included. Anti depressant medication made me come up from the dark pit. But I also had therapy to cope with anxiety and sleeping problems. It won't change over night, but you have plenty of time to become well again.
Ask your parents if you have insurance and what help you can get. Depression is very hard to live with and you need help, now!
I know you might feel ashamed or embarassed, I felt that way. "What right do I have to be depressed when my life is perfect?" But depression does not care if you are rich or poor, healthy or ill, shy or outspoken. Anyone can get it, and you can't manage it alone. You need other people to help you.
Start here. Ask for help. Today! It can be scary to tell anyone but you need to.
