Am I in some sort of depression and what do I do?

I once was madly in love with this girl. Her name is Debbie and I still am in love with her. I tried all year to get this girl and I got her number and had her over a couple times. We would talk on the phone for hours and then she stopped calling me. I bought her this 300 dollar Italian necklace but she never came over to get it then everytime I looked at it I would cry for hours and would cut my wrists, arms, and sides. I always wear long sleeves now so people can’t see my saddened heart. I then returned it and decided to end my life. There was this one spot I always wanted to take her where I would give her that necklace under the stars but I knew it was never going to happen. I had a bottle of Substance ACD which if you were to take 2 pills you would overdose and die. I sat on the bench looking at the stars spelling out her name then I said a prayer to God asking him to let me in Heaven. Being 17, I swallowed 17 pills representing all the years I spent on earth I swallowed those pills and I lied back on the bench singing and crying. I then arose, my head felt as if it was being cut off by a dull knife and I regained consciousness. I had a pile of vomit next to me and I looked in it and there were 16 pills in it. I couldn’t believe it. What are those odds? It’s impossible, it was a message from god. I was still heartbroken and to tell you the truth I still am. Are you depressed? Sadly to say, but yes you are. In order to make yourself better ask yourself in your mind what am I sad about then relsolve it. If your unattractive make your self attractive, that was my problem mentaly so I just ran. I ran on the tread mill every day thinking of her and lost 35 pounds so when she sees me she’ll come back. My whole point is don’t attempt suicide. I lost 50 pounds, got a six pack, and my band StarGazer got signed into a studio and if I would have died I wouldn’t have girls hit on me every day. People love you and care about you whether your deppressed from the one you love or just because. Cutting your self will leave scars and scars don’t heal but always have faith. Ryan
