needing comfort & advice- im miserable

hey mommas... I think we’re all starting to get to that point of discomfort in our pregnancies as we approach the 3rd trimester. And I know I should expect to be uncomfortable, but I feel like I’m extra uncomfortable? I have severe pelvis and back pain with sciatica on both sides so most days I can hardly even take a step without wincing in pain. I had chronic back pain before pregnancy and I’ve always had a high pain tolerance but I feel like I can’t take this anymore. I’m 28 weeks & I still work at my part time job at a little boutique, it’s not physically demanding at all, but I come home everyday feeling like I need to be in a body cast. I’m so happy to be pregnant and growing my sweet baby girl but I’m SO miserable and in so much pain. I feel guilty that I feel this way. Half of me feels like I’m being a wimp and everyone who’s pregnant is uncomfortable so I should just suck it up but the other half is telling me that the amount of pain I’m feeling isn’t normal, and that I need to listen to my body and start taking things really easy. I feel like my daughter can feel the stress and pain I’m in so that makes me feel bad too. I just don’t know what to do anymore. I feel so helpless since regular things like walking and getting out of the bathtub by myself have become almost impossible most of the time.

I guess I’m just looking for words of comfort, support, and advice on what to do. I’ve tried all of the things for the pain: Tylenol, stretching, exercise, chiropractor, etc. I just feel defeated by my pain because I’ve lost hope that it’s going to end
