Feel worthless sometimes...

I'm pregnant for the first time about 14 weeks now. everyone treats me differently now. people act like I'm disabled because I'm pregnant. at work people are constantly yelling at me that I'm doing or lifting too much. my doctor hasn't given me any restrictions. It's not like I'm lifting 50lbs maybe 20 so i don't see the problem. I just don't understand why people have to over react when I'm not doing anything wrong. some people act like I'm incapable of doing the simplest things (like handing someone tools while they work on your house because I'm not allowed to work on things myself) how is handing someone a drill going to hurt me. even my husband tells me he just wants me to relax all the time. some people might like being babied and told they can't do stuff.. But for me, I've always been pretty independent, I'm kind of offended and feel worthless all the time.. does anyone else feel this way??
