Maybe picking up the phone and talking to the samaritans will help in the moments when feel the urge to harm yourself freephone: 116 123 email: firstname.lastname@example.org
I know from my current experience that it can take a while to get the right help put in place, but knowing I am working towards finding solutions rather than being stuck in the problem gives me something positive to focus on.
Try to give yourself a break and be kind to yourself by doing some simple practical things to take care of yourself physically.
Please keep talking and posting, you are not alone
