Hello and Welcome to HealingWell and the Depression forum. I am much older then you as I am not sure what the "emo" thing is? Help me out here and tell me what your referring to.
Depression is a real disorder and most people can live with it with the help of therapy, medications or alternative approaches. Does it go way? For some people it will go away for years and then come back. For others it is a part of their life like diabetes or asthma and they learn how to live with it.
From the sound of your post your trust level is very low.........I understand this as trust is putting yourself out there and you never know when someone you trusted will turn on you or leave you but you still have to keep trying.
Do you have a counselor? I think it might be good for you to have a check up by your PCP to make sure you do not have any medical issues and then take it from there.
Do keep posting as there are many wonderful members here and they do read the posts and care about all the members.
