Be as cheeky as you like!
I will explain a bit where we are. I have worked my way up an industry just purely by starting as a Saturday girl. I'm now senior management but when I got pregnant I sort of lost my shit with DH's constant parade of low wage jobs that never lasted longer than 6 months and I encouraged him to aim higher.
There are different courses for different things but I would say think about what you know, what you are good at and what you would like to do.
So for example, you could go for a healthcare pathway and do an access course for health. You could use this to get you on to a nursing degree.
You could do teaching, or TA with SEN or something in education.
You could do business; accounting (really good!) or sage, or HR.
Lots of things. Aim high, choose your path, investigate how you get there.
And so much love to you and the best of luck. Sometimes life is really bloody hard and I take my hat off to you that you want to work while everything else is going on. Un MNetty hugs for you
