Despondent

I'm over it really. I've had enough of being we. Cant seem to find motivation for anything. Tried doing some of my dolls today which I usually enjoy. I haven't done any in about 3 weeks because I just haven't felt like it. I really didn't feel like it today either but thought I would see if I felt better once I got started. I didn't. I worked for about an hour or so and then stopped with a massive stomach ache. I packed up and headed for the couch for a rest. My stomach has stopped hurting now. I think it was just someone inside not happy doing dolls. But I can't find motivation to do much else either. Every time I think of something to do, someone inside says they don't want to do it. I feel really flat and despondent. It all seems to hard.
I lost the plot at my husband yesterday. I was getting frustrated with everything and felt, as I still do, that I am not achieving anything. He is doing all the hard work and I feel useless. It all boils down to me feeling like I am not good enough. I don't achieve enough, I don't do enough and I am not good enough.
I feel a bit like I am not able to do anything. I cant even get the motivation to clean. It is all very frustrating. (My husband was very supportive by the way.) I feel a bit lost really.
