Too sensible..

These last days I think I feel too sensible cos my BF and my other BF are always discusing. However I've always been quite sensible, I feel sad and happy easily, and I don't know if you'll understand, but I get angry inside and I want to explode but I can't express it and it seems I'm not angry!!!
I want to stop this happening because I have to change and have more courage!!!!!! :)
