Thank you all for your replies, they've been very helpful!

This no crying/sadness thing is new for me and only seemed to start after my meds were increased. Something I have also been considering is that this is actually how "normal" people feel (i.e. not getting upset/crying at the drop of a hat) and I'm just not used to it yet. Depression is familiar to me and in my comfort zone and even though it is unpleasant it is how I'm used to experiencing life. As I said before, it is not like I am completely emotionally numb; I am able to feel excited and motivated about things which is how I know I am feeling better.

The other thing is, the last time I came off my meds (due to bad side effects) it did not go well. My depression got way worse and I was have suicidal thoughts. That's why I found a Pdoc and went on the meds I'm on now. I think I will talk to my T about this and see if she has some suggestions on how to get back in touch with my emotions.
