Hugs, dear. The 3rd trimester is tiring and emotional. Do you manage to talk to him digitally regularly? If you need someone to talk to, drop me your number at faith.n.love@gmail.com and I’ll message you okay?:)
Call him via voice or video; message him if he is busy. Do some reading, listen to soft music or watch TV programmes. Keep yourself occupied so that you won't feel emotion.
