Thank you so much for all of the help you have given above, I do really appreciate it. I will give those things a try. Sometimes my issue is that I have tried so much over the last year that I feel a bit hopeless and I have really lost hope in finding out what is wrong. But I will keep trying.
I have thought for a long time that it is hormones because for over 12 years my body has always been overridden with chemical 'hormones' and now maybe my body is just struggling to figure it out itself. And I think the hormones themselves cause some of the depression, but that is intensified by me being frustrated and upset that I am not feeling better despite all of my efforts!
Once again, thank you
