Stopped suddenly two weeks ago

Been on antidepressants since age 9, a whole assortment. Been on Prozac for about six years. I’ve been taking a 10 mg and 20 mg pill together for 30 for a while and recently was given a 30 mg pill as a refill. I took one and felt like I couldn’t breathe panicked for a while. It’s been two weeks and I havnt taken it since. Emailed psychiatrist, no reply. Called office, no appointments. Don’t know what to do. Having withdrawals, nauseas dizzy ect ect. Don’t know what to do. Story of my life.
