I did all heavy lifting low paid jobs, flagging, fencing delivering various garden aggregate. This is how I did my back in 3 popped discs. was off sick but decided put myself through college went and did electrical installation 3 yrs passed everything, started working for a firm only there 6 months woke up couldn't see out my left eye, went a specialist hospital (St. Pauls eye hospital) I was told it was either a tumour or idiopathic intracranial hypotension.
Luckily it was not a tumour although having 17 lumber punctures up to now to drain cervical spinal fluid is no fun but if I dont have them I can go blind.
Needless to say I have no top end equipment but what I do have I get the best out of it and have seen many objects mostly double and multiple stars, you never know I may win the lottery and buy my dream set up.
I do hope your health is getting better I too suffer with depression being in pain 24hrs a day so I know what it is like.
Best wishes
Paul
