I want to self harm tonight
Why do you want to hurt yourself?
It is the only way to deal with my pain at the moment.
Do you need to go talk to someone? Self harm should not be your only escape, there are better ways to cope.
I will hold off until tomorrow.
If you are having thoughts of wanting to harm yourself than it may be time to try and find someone who can help. It sounds like you are pretty overwhelmed, so talking with a therapist or getting some exercise may be a great idea to calm your brain a little.
