I just cant fight this depression anymore...?

So let me give me you a backstory of what happened. 2 years ago i was diagnosed with tuberculosis. My doctor gave me some pills to silent the virus because it was dormant. My doctor (like an idiot) told me to double up the pills and it resulted to liver failure. I was just 13. i was in 8th grade and was living life, talking to girls, getting my first kiss, hanging out. Everything was just gone in a day.So after i had my surgery, i tried to fight my sadness for my fathers sake,i loved him so much i mean i couldnt show him i was sad. So then around a few days later i was on facebook and i saw all my friends have all of theses albums of these senior days like jersey day, crazy hat day, twin day, etc. And i remember i was talking to all my friends about what we were gonna do on each day...and i saw the pictures and everyone smiling and laughing. I was broken. I dont think i ever cried so much.i was at mount sinai and they gave me a view of central park and i would see kids there and playing and laughing and i would just stare out the window for hours at a time. at other hours i would stare at myself in the mirror. So at night i wouldnt sleep at all and i would just stare at my thing that tells you the heart rate and stuff. So then after 20 days i was released from the hospital thinking the depression was going to stay there and it didnt. i dont have any self confidence anymore with my huge scar that takes up my stomach and every since then ive attempted suicide twice but never finshed it.So when i started high school in september, i have more depressed than ever. I mad friends and all but the depression is eating me. When I thoght i was done with my life, around 1 year anniversary of my surgery, i met this girl and well it was love at sight (kinda corny i know) And well ever since then she keeps me alive. i love the way she smiles and the way she can wear sweatpants and t shirt and look just as beautiful. So please leave your responses cause now its summer and yes i have been going but i feel like at home depression is waiting for me and its consuming me Thanks!
