i don't know if its serious or what, but its destroying my relationship with my parents. i've been this way for nearly a year now. my moods change really easy and it can really effect people. my parents and i always have arguments because i tend to get moody with them, same with my friends. some of my friends suffer from bipolar but i've looked it up and most of it doesnt seem like me. also i can never stay in a relationship because i dont realise what im doing till he ends it with me. earlier this year i started self harming. i only did it because if my parents shouted at me, then it must be my fault, so i looked at it as a way of punishing myself. im hopefully going to see my gp in the new year with a friend, but in the mean time i dont want any arguments between me and my parents, especially at christmas, so has anyone got any advice ?.
