Should I be worried about myself? (Self harm)?

It is not a healthy way to get over pain. Self harming (huge or small amount both) shows weakness. Somehow it points that somewhere you have lack of love and respect for yourself. I guess you didn't noticed but it is getting a habit to cut yourself. Instead of cutting yourself and making it a method to release your pain find out the reason why that happend and how can you make sure it doesn't happen furthur. See a doctor if you have problem when you don't cut yourself.If nothing helps then pray to GOD. GOD gives us strength to do everything. God is your strength. Just give your faith to GOD.hope I helped.
