hello! i have the same problems, all of them , as you do and i had a hysterectomy in august of last year. I did not keep my ovaries. I was put on premarin and hated it!! now i take estratest with testoserone and prozac...now they did put me on paxil and that made my heart race and zoloft did the same thing and i was spacey too. the prozac hit the spot!! 20 mg in the morning and i am a different person. sounds like menopause to me but then again i am not a dr......good luck, i do know what you are going through...sincerly diane
