If you've never taken Mood & Mind altering drugs? I strongly recommend you see someone who specializes in those medicines (psychiatrist, or prescribing psychiatric nurse, which is a doctorate level degree), and spends all their time with them, instead of (GP) 2% of their time with psychiatric meds, 2% with dermatology meds, 2% wih fertility meds, 2% with GI meds, 2% with blood pressure meds, etc. on down the line.
There are hundreds of psychiatric medications. 80 commonly Rx'd for ADHD, alone. About 3 times that many for BipolarDisorder. And on down the line. PTSD doesn't have any meds specifically "for" it, so it's trying to alleviate symptoms based on off-label use of other medications (anxiety, mood stabilizers, antidepressants, nightmares, etc.).
So, again, working with someone who has a very good understanding of the few hundred available options? Knows what side effects to expect & look out for, gets all the news & study & alert updates each week. Keeps up on their education? Knows whether it would be a better idea to have you try so e emergency fast acting meds for the holidays, so you aren't in the middle of starting a new series of meds during a hugely stressful time, or whether a slow to act but steady dose during a hugely stressful time...Very, very strongly recommend.

Psychiatrists generally bill at $400-700 an hour for medication management, which frightens people way... But they aren't also doing counseling, which makes even more people leave very confused. Med management appointments are typically 5-15 minutes long.
It's generally best to have a team, IME. A therapist you do counseling with (and can write up a list of the symptoms you'd really like addressed with meds, if you don't feel comfortable rattling them off in 5 or 10 minutes all shotgun style), and a psychiatrist or psychiatric nurse who prescribes & follows your med treatment. Most therapists have a short list of prescribing physicians that they already work with, but if they don't, or theirs aren't covered by your insurance? It's pretty easy to sign an exchange of info form signed for each of them so they're allowed to talk to each other about you (otherwise confidentiality prohibits them talking to each other). I find it saves a lot of time to have my providers do the medical short speak together, and then just fill in the blanks as necessary.

I don't happen to take meds at present, although when I'm being smart I keep a bottle of Valium in a drawer, somewhere. Because I know -Valium- I feel comfortable getting anyone under the sun to Rx it. But being ADHD, and moving all the time, and trying many many many different ADHD meds over 20 years? (And trying new meds mean I revert back to a psychiatrist/specialist, rather than hitting up anyone I know for something specific). ^^^ Is what I've learned from doing that.
