No mood to work at all

I am now in wk 28. Just had a week of unpaid leave last week and back to work just yesterday and i am feeling so tired to go to work the next day. Restless and feel lethargic at work. I hope i can get HL for my next check up. Keep on taking unpaid leave. Its so stressful. How do you all deal with it? Please share. Thank you. #1stimemom #advicepls
