Anyone else feel behind in life?

I'm 23, married, mom of 3, recently got and moved into a house that needs sp much work done. I'm currently a SAHM and my husband is talking me into finding a job that works with his schedule and go to work to help save money and fixing up the house. So I've applied different at places. I recently put an application in for an at home job and feel like I completely failed the assessment test. It has me rethinking my whole life. I want to go to college for accounting but I feel so overwhelmed with all the colleges out there, whether I'll have enough time for it or not. Its stressing me out and I feel like I'll never succeed because I can never seem to get myself on a schedule. I feel like I'm in a hole and can't get out.
