My best friend is having her baby shower next month. She wanted me to help arrange and organise with the set up of the day, which I am willing to, but I am also pregnant - a week ahead of her. I am so tired and work full time whilst being very busy preparing for baby at the weekends. She works from home and is part time. I don't think I have the energy to help out. I am of course attending the shower but I feel so bad telling her that I feel too drained and tired to come earlier to help, when she must know how I feel given we are near enough the same amount of weeks. AIBU? Should I just power through? Or should I be honest and tell her I am just not up to it right now. She does have other friends that are helping.
