People think I'm so easy and I hate myself for it.
I'm sorry you feel that way. Why do you feel that way about yourself?
I am a pushover and will do anything anyone wants me too.
There's nothing wrong with doing things to help other people, but if you feel like you are being taken advantage of, you should make an effort to change. Stand up for yourself the next time someone asks you to do something that you really don't want to do and tell them "no."
That's too much work.
I know it's difficult and is going to be uncomfortable for you, but I think you should try it. Changing how you act so you're able to stand up to other people when they try to take advantage of you is a good thing. It will make you feel happier in life.
