Hi Hunni, going for blood test and group aren't nothing, so you didn't do everything there is always time to catch up on stuff.
You know harming wont make anything ok. It will just make you feel worse, more appointments with gp, a&e and clinic. You don't want that, you don't need to do ii. Its just your head messing you about and you know you can't trust it.
Really think you should talk with someone, if not duty, maybe sams? I'm always here if you want to talk and think I can help.
You aren't on your own, please let someone help you.
