Changing Social Media handles.

I would like some guidance please. I have just closed my wholesale handbags and home wares business. I have closed down my website. However, I have not closed my Instagram or Facebook. I have a few followers not 1000’s, but still a few.
I am not sure if I should just close those accounts and just start new ones, with a new name. Or, do I tell everyone on my SM, that I am about to start a new career and direct them over to a new page.

I started Coach Certification yesterday. (yeah) Part of my reluctance is I like my SM name, but it has nothing to do with what I will be doing. I am not 100% sure what I will call my new business. There may also be some resistance as if I close it or change it it will be the final letting go.
