Thank you guys, you're so right. I'm sorry for moaning! I'm not going to do anything rash with my relationship, it'll just complicated things further! And that's certainly what I don't need!
It was the right decision to quit my teaching job, I wasn't valued and although it was nice to have a definite pay packet at the end of the month, it wasn't worth the emotional strife I had to face to receive it, I just wasn't living. I'm now working as a regional manager of YogaBugs, teaching children from walking to 7 yoga through music, movement and storytelling. I work in schools and nurseries mainly and find my job a good distraction from my illness (as you're right, that's what it is)... I never feel that I let my depression get in the way of my work as I am there to help the kids, and I suppose, through helping others I help myself as well.
I've never considered myself to be a selfish person which is why I think I find this so hard, I know I'm an only child but it's never been 'me me me' until now. If I think rationally I know that I am not useless, the majority of people screw up their driving test down to nerves / some other idiot but I just thought, if I can just get this one thing right then at least I'll be able to go places on my own and show people I'm not completely useless but now I've got to wait another couple of months for another chance.
So sorry once again, everyone is just so lovely on here though. I don't know what I'd do if I hadn't found this forum.
