Should I feel guilty?

I'm disabled but feel super guilty for not working at a normal job. I do some things I can do but so far they haven't made me any money. I have a masters degree I earned 5 years after I had brain surgery and someday I'd like to teach a couple classes from home. I know I'm never going to make a normal salary. My husband works. I'm pregnant and on bed rest so I'm doing even less than what I used to do! The stress of possibly losing the baby made me soooo upset and I ended up turning to crafts to calm me down. It worked. But... now I feel guilty that I've found something that makes me so happy. I'm knitting baby clothes and making the baby mobile and making toys and I'm happy -- but sometimes I think right but my husband works...I don't. I'm awful. I'm great with kids and I will take care of my child, and eventually I'd like to help out financially somehow-- but how do I stop myself from hating myself for not currently working for money? My husband knew all this going into marriage and wanted to marry me anyway. Sigh! Thank you!
