You feel how you feel but that can't help you with your financial problems? I would make a plan, if your father normally pays for your schooling, then accept that from him with respect but otherwise try to study/stay away from home except when you are required there. Treat your adopted mother with respect, no matter what she says to you, just practice hiding your feelings from these two, doing what is required but working on your plan to get out. If you have no other support you must accept money from them and do so with a modicum of thankfulness and acting like a dutiful son but then you can go out and find a job to support your own life.
