Dear Bizi
topical use of steroid cream for such a short period should not have systemic effects. my suggestion would be to continue with the prescribed posology - you said you slept last night - until you see the derm. you seemed worried before because you couldn't sleep, makes sense. while it is theoretically possible to have systemic effects, but itching and worry are more likely to cause sleep loss than 2-3 days of steroid cream applied to a small area such as the break out on your face. if you were applying the cream, say, to your entire torso, then, i might be singing a different song.
i can't say re: the abx but it seems plausible that drug resistance to one of the tetracycline group it will affect other abx in that group, certainly worth asking about.

just tonight and tomorrow then you see the derm again. not long. hang in there. have some extra Klonopin or a Blueberry beer. i stopped at a store on the way home yesterday. it was on special. now having myself some weissbier.
Cheers.
