Depression.

Where can i get help for my depression?:'( i just feel extremely lost and alone. I dunno what to do about it. I'm extremely poor i cannot afford therapies and doctors. Can't tell my parents how iam feeling and dont have any friends whom i can confide it :'( i just feel like i have so mych bottled up inside of me. I feel suicidal almost constantly with no real reason to be unhappy about:'( my friends tell me that im ungrateful for feeling sad when there is nothing practically wrong with my life. I dunno if this even depression or what im just so lost:'(
