Scared what my parents will do next....please help?

First of all you are to young to have your own apartment. You are 16 years old, going to school and living at home. If you are wasting the money, your dad has every right to cut down your allowance. In my opinion you are not responsible enough to get an allowance. In my opinion you also need to end your Instagram account. You should be outside with your friends. And when it is time to go home, you should be having family time.

Since you're so mature one supposes you could just get a job like the rest of the wannabe adults have to. 

Stop trolling you're too young to have an apartment and if it's his money yes he can take it 

maybe you can get a part time job
