How to overcome sadness (living with dysfunctional family)?

Your of age to do what you need to do for your happiness.Go to college.Find a job and get your self a room for rent or a studio apartment.Why would you want to live in this kind of surroundings where your own family makes you feel like your a noone? If you need to get a job first to save then do it.There is nothing wrong with your stepmom being the way she is with the way she is acting with her baby.She is 50, and excited to have a child.Can't blame her.But her ill mannerism with you is wrong.And you have talk to your dad already and nothing has changed.So why hasn't your dad step in.You say he's a workaholic.Are you helping more in the house?Do you wash your own clothes?Do you throw trash?This could be your way to help break the ice at the home.So think about all the options before you make your move or a decision.Personally I would get a job,go to school,and help more in the home.I would save and when the times are right I would move out and start to be more independent.So make the best on your part and I think you'll be ok until you make your plans.And just save without telling your family.And when your stepmom comes out mean to you as her why the coldness and that will help you make decisions.
