My home problems are causeing me to become sleep less and self harm what do I do?

Ok my rents split up 6 years ago and she met her bf 5 years ago and we movd to the UK to AUS.I was angry allot when we moved away cause my dad was in the UK and I couldn't see him and he never gave me mony like he should. I was very angry a lot I once got called a baby in handwriting and said "I'm not u idiot" and through my book cross the table into his nose and the teachers would try and calm me Dow and I would shout at them my freinds would go away and I used to cry all alone. I was also like this s home to my mum and she took me to the doctors and they said to take me to a cicolest witch help with anger, stress, craziness or problems they help you and now I get along with my mums bf, have my own bf, have lots of freinds both sexes, get along with family and school! :) and self harming try to not try distracting or just when you feel like harming try and think no stop this is bad! I know how this feels! :)

Okay, first, I need you to know something. Harming yourself will never help a situation. You need to find an adult you trust and tell them what's going on. If your mom doesn't understand, try your dad, aunt, uncle, school counselor... Whatever they do, remember it's to try to help you. Try to distract yourself with music, sports... Whenever you want to self-harm, draw a butterfly on your wrist or arm and name it after someone who is close to you or wants you to stop or even name it after me. Don't wash it off, let it fade. Hopefully, that will help. Apologize to your friends that you threw a scooter at. If you start to get angry, just walk away and take deep breaths. The most important thing you need to do is tell someone about this, okay? Good luck.
