Feeling very very sad 
Iv been in a dead end job for 4 yrs.
I did really badly in school because of my home life and no support.
I'm 38.
Is this it for me?
I hate my current job but so scared to apply for something else.
There is a position in a local school as admin assistant and I could do the job (so my friend who already works there tells me)
But on the form it states grade c's or above for maths and English.
I can't lie because you have to produce proof.
My friend is telling me to still
go for it and big myself up in the interview but that fills me with dread.
The last thing I can do is say good things about myself.
Where do I go from here?
