It could be a sign of the meds working, or it could be you've moved into different phase of your illness. Either way there are some changes that have maybe made things a little easier for you.

Meds work at different speeds and on different symptoms for everyone. My meds increase my emotional numbness to the point of almost total indifference but that means that I'm not wasting energy on harmful behaviours. On the plus side that means I eventually have a bit more energy to use on taking care of myself, on the downside it means that I become more withdrawn and anti-social. It sounds like maybe you're responding to your meds in a similar sort of way.

Meds can be notoriously slow to act, that's not always a bad thing, it gives you time to re-adjust to the world. One of the worst times I've ever had was getting better too quickly, as the change disappeared just as suddenly as it had arrived. It felt such a cruel punishment to have been robbed of my beautiful mood.

You're not being unappreciative at all, that is depression raising its ugly head and underming your confidence. There's no such thing as normal, everyone of us is unique, but to me your recovery sounds fairly typical. The thing that docs don't really explain is just how hard, slow and painful recovery can be, unfortunately for far too many of us it will be two steps foward and one and a half back. Try to concentrate on how far you've come not how far you have to go.
