The best way to get over a girlfriend is to get another one. That is actually bad advise but it works. Also, the more you focus on this last one, the harder it will be to move on. Only you can give her the power to hurt you, and only you have the power to make it stop. Part of life is learning to move on, and that is what you are going to have to do.
To get over the depression, stay active, eat at least one good meal each day, and do something you enjoy daily. Surround yourself with other people as long as they do not do anything to remind you of her. Tell your friends that conversation about her is off limits.
Lastly, if you feel you need professional help, talk to your parents about this. Tell them you want to talk to a counselor. If they brush it off, tell them you are considering suicide. That will be enough to let them know you are serious. If worse comes to worse, there are suicide hotlines in every area, and they will put you in touch with professionals that will not charge you to see them.
Good luck
