Are you an adult but still feel trapped?

Never wanted to move back home. Its not my place and i have to share it with my brother (which i dont mind) and my insufferable father. Cant have a normal conversation with him. To him the world is bleak and cold. Everything is wrong and none of it is his fault. I asked him the other day about some stuff i read about weight lifting and losing fat because i wanna get rid of this belly. Again, cuts me off mid sentence and insists on "correcting" everything i say. Thanks dad, you inspire an awful lot of confidence.
