I just came down from hypomania as well. Felt like a total zombie yesterday. Feeling slightly less zombie-like today but that might just be because my boyfriend is off from work for the weekend, so he can be there for me. Things will probably come crashing down harder again on Monday. I hope you feel better soon. Take it easy and try not to be hard on yourself for feeling out of it. Mania can be really exhausting on the body, so when it's gone, you really feel the aftermath.
