Know what you mean ANNE. You can get in a bit of a rut can't you?
Being a mum is the most important job there is, but to go out and actually prove you can do something gives you a great feeling.
Yo do right to feel proud of yourself!
When I started at college I actually had one or two of the teenage students asking me if I thought I could cope with the courses :

2 dropped out of the course & the rest got lower grades than I
did any way. Plus I did an extra maths exam that they didn't.
Just because we get older doesn't make us incompetent. ;D
