I feel really really sad, can anybody out there help me?

Try to move on and focus on you and things YOU like. Family is great when they are there for you but when they are not because of their own personal flaws (sounds like these people have serious issues) -in other words they need help and you need to just worry about you and work on moving on to a brighter future. The future is in your hands my dear, the past as a child you had no control of....You do have control over the future you will give your children and you can start now to help make it good for them-do good in school. Try to get your mind off the past with extra studying....I hope you are seeing a Doctor and also going to college to make a Good life for your self!! I didn't go to school and now have to work very hard. I am 27 and gone 60hrs a week for week leaving two 18 month old babies behind who I miss so bad all day!!! Good luck
