I think your problem is very different but challenging at the same time.you have a dream to become an artist so first of all pursue your dream and don’t let anyone down.i also think you do best in your own.you are passionate about your dream but your problem of anxiety is common but you have to cope up with this different way. see there are lots of things to do when you feeling stuck at that moment like I am not talking about cars, big house or any other valuable assets.I am talking about your inner existence feel yourself concentrate on those things whom you fix it.forget about those people who wants to hurt your feelings.I know money is the biggest problem of every person so find a job first and then set out something new trying those things you have never done before in your life i think that will make you feel comfortable and easygoing and don’t bother about your father ignore him and talk to your mother about what she feels about him and say to her that what can i do for you mom and also support her emotionally makes you feels both stronger and sorry for my wrong english because i’m not a english boy.
take care of yourself & your mom also
