What medications have you been on? I only experienced,no longer having or feeling emotions, and that was when I was on anti-depressants, such as,Zoloft,Lexapro,Celexa,Wellbutrin, and Prozac (not all at the same time) seems like SSRI's was not the answer for me, but GP first had me DXed as clinically depressed, years went by,long story, and then I was evaluated and DXed by a pdoc as Bipolar-II(mild) and ADD(mild), put on right meds.(mood stabilier) and I am happy to say my feelings except sexual, have returned, some of that or all of it is due to my thyroid condition, that is being looked in. One of the mood stabilier they first tried also made me a zombie, Depakote, it works for some, but wasn't right for me, so with the pdoc's work we found one that was perfect for me, Lamictal. Before Lamictal, I was on Lithobid, which is terrific (my bro has taken it for over 30yrs) but then certain things became blunted and that's when pdoc suggested Lamictal. All meds affect people differently, so sometimes a switch or will to switch can have a positive outcome.
I always suggest having a physical to rule out any physical condition and then a psychiatric evaluation, in order to be put on the right treatment plan that best agrees with your system.
I can relate to this "non-feeling" thing, it's really beat. If you can explain to your doc how this is effecting you, and stress to him or her that you are willing to try a different med or combo, and you just do not like this "non-feeling" thing that is occuring.
Lots of luck with this, let us know how things work out.
Take care,
