Hello Piper Leigh,
I am sorry for your agony right now. I am also very low and waiting for an increased dose of lamictal to "kick in". As hard as it is, getting out with good friends is the best kind of distraction. I would encourage you to go. I have been in the same situation and I know how hard it is not to isolate.
I agree with the others about offload some of the responsibility of the shower. The less responsibility right now, the better. Don't feel bad that you are unable to handle ordinary things............ I found brushing my teeth overwhelming at my lowest!
The other thing that I have found helpful, albeit difficult, is to force myself to go for a walk or a run. It is hard to muster up the motivation, but it is amazing what a little exercise does for the mind. Ask your husband to go with you. Right now the only reason I am able to go is that my husband comes with.
I empathize with you, really I do. At my sickest point, a good friend would tell me everyday.......... "you will get better". A lot of the time I didn't believe her and sometimes I didn't want to hear it at all, but she was right. So, I am telling you now, "you will get better". Hang in there.............. Blue Poppy
