Feeling guilty

I’m 34 weeks and starting to feel very low energy and tired. I wanted to do more activities and outings with my 2 year old while she’s still an only child, but I’m struggling. I’ve been sick on and off all month and now that the colds and sinus infections are clearing up I’m getting Braxton Hicks all the time and I’m generally uncomfortable. I just want to relax and I find myself getting annoyed when she climbs all over me and demands constant attention. I feel so guilty that I just don’t have the energy to do much with her. Anyone else in the same boat?
