Aside from the ongoing conversation about sport pilots — I feel like you have a somewhat decent shot at getting a medical issued without deferral (i.e., immediately in office) and a very good shot at getting a special issuance medical in general (with a deferral and HIMS evaluation — which is costly but it doesn't mean you don't have a shot.)
Social Anxiety Disorder is one of the few diagnoses that the FAA recently released new, relaxed guidance on — but the thing going against you in this instance is that you took two medications at once as I understand it, so I am unsure if you could get a medical issued in office. But the time/length since taking it and the diagnosis itself bode well in terms of you being able to get a medical. You just might have to jump through some hoops.
My recommendation for you, if you want a full medical and don't want to do sport pilot, is to contact an AME for a
consultation-only appointment. Do NOT fill out a MedXpress application. When you're in the office, lay out your case. Try to bring supporting documentation of your diagnosis, and positive treatment notes, etc. See what they say.
There are also numerous private entities that offer a confidential consult, like LeftSeat in OKC, AMAS in Colorado Springs, etc. Obviously they are not the same as the governing bodies, but they have a lot of insight and could help you privately see if you have a chance before you go through it for a relatively nominal fee (but a consult from an AME is also nominal as well — so your call.)
