It sounds like you need support from your loved ones, its the reason why every time you are upset you mention anxiety. If i was your dad i would love you and help you in success against anxiety. But i am not, i think you may need to speak to your mother about your dads attitude.

Some things and issues in this life, are things and issues where you will not have support, even from family and friends. Its a demon that you have to fight and challenge on your own. What i would say is deal with the triggers, and try and get support from your mother.
