Extremely homesick disliking move from UK to India (Speciality Doctor)

Hi! I am struggling with my decision of moving to UK from India. It’s been only 20 days. The feeling started as soon as I landed in hospital accommodation. Every night I check for flights back home. There is an eerie sense of paranoia that has crippled me along with amotivation. I’m missing my daughter and a dog back home. I have helpful colleagues who are trying to support and convince me but nothing is helping. I am stuck with my decision to move back.
