I had this problem with my partner, thought depression didn't exist, something which was only in my head, Like you, I had no energy, didn't want to do anything even if I could get out of bed. Had to take 5 and a half months off work, couldn't go out, just wanted to cry. Difference is Ive got a ten year old and I can honestly say she pulled me through (along with the medication and a great doctor), Im still up and down like a yoyo. As for my partner, he is slowly becoming more understanding and willing to LISTEN to me. There in is the key, your husband may not understand but if he could show willingness to listen without butting in, Im sure it would help you. Good Luck x
