Hi Carol
I understand how sitting must make you feel "down" I went throught that at the same as time as all the rest......not staying in all the time but if I was supposed to go out in the morning I just couldnt face it. Not quite as bad later on. It was a vicious circle.....I was "down" so didnt go out....didnt go out so that made me worse
As for my shopping "weekly/monthly" I go with Peter and he does it.
Apart from the THR I cant carry heavy things because of scoliosis and having 2 crutches doesnt help
We get to the supermarket and he does the shopping and I wsander and look at things {clothes/make up and bits and pieces } and meet him at a set time on a chair. Our supermarket coffee places arent great LOL so if there is a chair I'll wait there and we go for coffee in Starbucks/Costa or somewhere like that afterwards.
How I got to a psychologist was I was sent to a pain clinic by the back specialist and one of the things they did was get this psychologist to ring me.....after a 30 min chat on the phone she said it might help if we had a couple of appointments.
One of the things she told me to do {about self esteem/scoliosis}
Was go to the Metro Centre and get a coffee.....no need to twist my arm to do that
aand sit and "people watch"...look at people and see how many of them have something wrong with them. Stick, crutches, scooter, bent, limping etcc..... then think if I wasnt looking for this would I notice that person....probably not.....and if I di notice them what would I think....nothing!!!! As you say simple advice but you dont look at it that way.
As for getting older....one person told me once.....old age is 15 years older than the age you are presently LOL I liked that 
Going back to shopping......I go into our Metro centre during the week with just crutches {I have a car} and see how far I can walk {not very LOL} but once a week I hire a scooter there and relax and go from one end of it to the other....not grocery shopping.....just Boots/superdrug,clothes , etcwindow shopping.....even if I buy nothing but a magazine I enjoy that.
I envy you....I cant sing....I'm tone deaf LOL LOL
I admit I couldnt stand for an hour or more....we do have to compromise.
I go to yoga......but no way could I be on a yoga mat LOL if I got down I would never get up again so I do it standing or one or two {like balancing on one foot....with a hip fracture I cant do that} I sit..there are a couple of people that do that and the tutor changes the exercises slightly.
So thats an "in between" for me....certainly not all.....but not nothing either if that makes sense.
You talk about going on LOL LOL
Mine has been long enough......I hope the weekend is at least dry....hard to tell at the minute. {North East} its just after 8am.
Take care
Eileen
