please educate

i just had 1 filling taken out today. I just ready late that i should have let a specialist take it out rather than a regular doctor. I have been suffering from panic attack and anxiety for more than 5 yrs. now that is whay i am desperate for a solution.

My question is now, what should i expect now that 1 filling is gone? i have 5 more to go, should i go ahead and have them all taken out?

also, i read that some people feel worst after haveing them taken out? the dentist used a drill and when i gargled all the filling looked powedery black and bits of silevr. I am not sure if i swallowed some of them in the process because i was swallowing while he was drilling.

what should i epect with the healing crisis?

Please advice. thanks
