You are the "Fix-It-Up-Chappy in your family. This is the family member who tries to be perfect and do every body elses job and keep the family running. But this can drive you nuts. You are trying to fix your parents and your family and you can't. You parents have to fix it and you need to move on.
Do not believe a word your parents say say to you, you are the one who is succeeding in life and they are not. You are the the responsible one they are relying on, to fix it for them. They feel irritated, because they can't do things themselves.
You being responsible and suceeding in everything, just reminds them how inadequate they really are. Do not let them tear you down any more, get out of there now, before it is too late. They are down and they are pulling you down with them. You deserve better, you deserve a life without abuse.
God lbess and take care.
