In agreement. It seems to me you are falling into the trap of the blame game. I am seeing a person who finds it easier to blame someone else than taking personal responsibility; whether that be responsibility for their lot in life or responsibility to change it. I get that the people around you haven't been supportive - including your therapist. But this does not discount that you owe it to yourself to make change. These people don't owe you anything more. They won't change. BUT YOU CAN.
