I find it concerning that you 'made' her stop seeing her best friend. In a healthy marriage or partnership, couples ought to be able to have their own sets of friends and/or activities. Having one partner decide who their spouse can and cannot see is abusive imo.

If she was already sad and depressed, no wonder this would hit her hard. Not only now does she feel cut off and isolated as you cut off a social source of support for her but you now want her to enjoy activities that you enjoy?

There is nothing wrong with her having different hobbies. How about you learn to cook and share what she likes to do?
