Some days when I first started work I had to pull over on my way home from work because my legs are shaking, I have a headache and cannot concerntrate.
I thought this was because I was unfit but 6 months In although I have gotten used to it, I am no better.
Today I tried to pick up 4 lengths on trunking on my shoulder, something most people do without issue and straight away I had massive pains up my neck and a throbbing headache for about 2 hours afterward.
Everything I do I seem to struggle, I never find anything easy.
A few days I've considered just handing my notice in because I'm clearly not able to cope with this sort of work.
It's embaressing having to just say "I can't do it".
What do I do now? Totally at a dead end.
