Sometimes, for some people, that emotional blunting is a relief, especially if one has been 'feeling too much' or is hyper-sensitive to every emotion and feeling. I have had breakdowns, gone through them battling to come out, absolutely exhausted from the down mood and/or overthinking every little thing, and the numbing from meds is an incredible relief. It gives my mind and body, finally, a kind of rest.

It is possible that the dose you're on is too high. That's what it sounds like to me.
