I'm thinking of my business is struggling but it gives me anxiety.  I don't have another career path if it fails and if it does it will really disappoint my father who has financially supported it.
It was good that he was willing to support you, but he will understand that not every business can be successful.
Fuck my dad, who still thinks i'm 17.
Parents can sometimes have unrealistic expectations of you but you should still be grateful for his help.  Even if this business fails, you can still follow your dreams into another line of work.
I have to take care of my family.
It's hard when it is family but you shouldn't let other people try to tell you how to live your life, even if it is your parents.
