coming off of meds?

hello, i am 28 years old. i was on Ultram for 3 years and recently got off after having surgery that fixed the pain problem. while on Ultram i felt like my mind worked very well, my mood was elevated and physical energy was high. i went through a really rough detox when i stopped taking it which made me study the drug. when i found out that it elevated levels of serotonin, dopa-mine, and neuro-epinephrine in a nut shell a super antidepressant, i wondered what to do now that i am not taking it i feel very depressed, lethargic, unmotivated and just bad. i am trying excersize, ginko biloba, 5htp, caffiene, and rest but am not sure that i shouldnt consult my doctor for an anti depressant....i am also sweating in my underarms all day long like i never have, having to change shirts often, i do not know what is going on...i am also on a stress vitamin formula, B's zinc C . i just want to feel good again and wish i could actually feel the way i felt on ultram agian.-motivated.what should i do?
