Cymbalta ruined my life

I am new to this group. I’ve been on Cymbalta for 4 years. It’s ruined my life. I’m a shell of the person I used to be. My biggest issue is my husband and I have no sex life. Which is making him feel unloved and unwanted. I want sex with him but when it comes to it I just have excuses for why I can’t.

I love him so much! I just know this medication is the reason I’m withdrawn emotionally and physically. I’ve been tapering for 4 months now and still see no signs of getting better.
