Rise above it Ken. No one controls what you think, except you. Take any negativity you may perceive in stride, and let it pass. Give it no more reality. You have a right to be happy, so do so. Go about your business, and accept who your parents are by letting them be as they are. Resistance only makes it worse.
Think positive, enjoy where you are at, and work to get back out on your own! [:D]
I am once again living with my parents due to some unfortunate luck.
When they do go out,the energy in this house feels lighter and cleaner.
