help? idk what's going on I'm worried

So I know that I'm going to get a lot of judgement for this which is why I'm posting this anonymously. 
I'm 1 month clean off meth. I was using for a few months maybe 6 months at the most. I was a heavy daily user until I started getting heart pains so I stopped. And ever since I've been clean my heart beat is just abnormal sometimes I'll have chest pains to the point where I need to go lay down. And I kinda feel like I'm high still even through I haven't been using. I heard from some other recovering addicts that i could be going through post acute withdrawal I'm going to the doctors soon but I'm underage so my dad doesn't know if I were to tell the doctor would he legally have to tell my dad? Also have you any guys experienced this? Please no rude comments specially if you don't know anything about drug addiction. Just because I'm an addict doesn't mean you have the right to put me down and treat me like I'm less than.
