In my opinion, it's impossible to feel too much. But, it is possible to feel too overwhelmed. What if you asked your depression what it wants from you? Everybody needs a day off work or time to lounge in bed. This may not be horribly bad, even if it feels that way. Maybe you need to so something kind for yourself. If you need to post back, then do it. Support feels good and you certainly deserve to be supported at this tough time
