Welcome BeautyT
Just take a deep breath and release. There, let the calm in.
I can say it does get easier. You've gotten some excellent advice already. Stress can make sx worse. I tend to ignore sx and that can be helpful. The downside is I forget to mention them to the doctor. Finding your own balance will come with time.
I was dx 11 yrs ago and I think last year I really started to accept it. Not that I don't travel the river, denial, occassionally.
It sounds like you overdid it, and you know it. I tend to have more word problems when I'm fatigued. And I tend to realize I'm fatigued after I stop doing. I just want to get it all done, and this disease is not helping.
I have learned to take frequent breaks whether I feel I need one or not. And usually I do, and am grateful for a few minutes of stillness. If you can rest/sleep as much as you can this weekend. I hope you feel better.
I look forward to hearing more about you and feel free to chime in anywhere. Weekends are quieter, and this place really jumps during the week.
