​Should I quit my day job?

I’m currently working at a bank and running a home based cake catering business. I’ve been doing this for about 10 months but I’ve recently developed really bad anxiety around meeting deadlines and just constantly being busy trying to juggle so many things. I make on average $2,300-$2700 monthly from my cake business and $2800 monthly from my day job. I haven’t touched any of my business money with the exception of purchasing materials and ingredients since I started so I have around $12k saved up. My husband also works in IT and makes decent money.. I feel like it’s time to quit the bank and just take on my business full time but the thought of taking that jump genuinely terrifies me. Anyone else out there make this transition? What advice would you give? Thanks in advance.
