if you feel like crying, you should just cry. not crying doesnt mean you are stronger, it is actually harmful for your health as you bottle things up, which can eventually lead to depression. if you feel that you are going to start fighting with your friend as soon as you talk, its best to let it cool off first, but dont wait too long, because she could be dithering and unsure the same as you are.
step parents can also be a real pain, but your dad needs someone. just let him know that you would like him to spend some more time with you, not just her all the time.
just remember than even though this month has been bad, next will probably be better

dont wonder why im not smiling, wonder why you are.
