​Overwhelmed. Need help badly. What to focus on?

I need help from those of you further along. I am sitting here so overwhelmed today I want to quit. In between making products (half are finished), researching how to build a site and blog, how to use social media to start building a following before launch (I have no social media beyond linkedin) to learning basic accounting skills and going back two months to write down all the expenses paid for since I started this small business two months ago…I am just SO overwhelmed. I started a business plan too and never finished it. Should I finish that or does a basic one suffice?

Please give me some advice. What should I focus on first? I can’t wrap my head around it. Much respect to those of you who’ve already done this all.

Thank you 🙏
