Satuation where I overthink and doubt myself literally i don't understand what happening to me

1.  Whenever my father talking about money with me in angry mood i freeze my own identity my mind goes in to fear mode with helplessness 
2. Whenever he is angry with anyone or anything i lost my sense of focus and also my program how I do things after whatever he say I will do like slave of him with not any resistance 
3. Today i loose my sense of identity, focus, what things to do my own when my brother and mother treat me like a shit
