Welcome to the community here. I'd just like to suggest that if the psychiatrist has recommended this for you, than I presume they know why and they must think it will benefit you.
Maybe you could consider the advantages of being in a place where you can receive assistance verses trying to deal with your mental health yourself.
The programs that are run in the facility may be different for each person depending on the issues and individual circumstances.
If possible, make arrangements with your family as to how they will cope and manage while you are receiving the help, assistance and care that you require to help you restore your mental health and well being.
Wishing you well, cheers from Dools
