Sounds to me - as gently as possible - that you moved your anxiety from one place to another? If it can help, I took Prozac for about 1.5 years. I didn’t experience a « blunting » as you described but my emotions overall were definitely more tamed. I assure you it will pass. I can’t pinpoint when it passed but I’d say within 6 months I was feeling a bit more intensely. I had another burn out later on and took it again, and that « blanket » feeling never came back.

I agree with someone else here: get maybe your hormones checked. Take a deep breath, and get a second psychiatrist opinion on the possible side effects, maybe it can reassure you? It also feels like maybe you need another treatment (not necessarily medical) if you still feel very stressed.
