Week 36 and mixed emotions

At week 36 and i feel extremely exhausted all the time Still working as usual and husband has been telling me to request for wfh But i feel guilty about it and i dont want to feel like a handicap in the team. Although my close colleagues had been telling me to wfh. I dont know to raise the topic to my bosses. I feel like i need to be strong but i am very tired already...... And havent had the opportunity to do my handover yet Planning to request for HL soon.... Just ranting
