Do i have a mental issue?

Yes, you do have a mental illness but don't be ashamed because you can't help it but there's many medications out there that can aid with it.I would recommend going to go see a psychiatrist and he'll find the right medications for you.It may take a few times to get it right but it will.I'm not here to make a diagnosis but I'm a psychiatric nurse and know that you do need help so that you can live a normal life without all of those fears and not cutting yourself. Good Luck
