Hypertonia/unable to defecate

Hello all

I am female, 50.
Wondering if anyone has been able to defecate properly again?
I am only going when I use laxatives (triphala) at night.
And then the rest of the day it’s hit and miss but it’s been months since I sat in the loo and just did a normal bm.
I’m seeing physio and walking and eating properly (I’m a nutritionist newly trained)
But I’m becoming so constipated I’m staring to worry it’s impacted ? Haven’t pooped properly in over 8 wks!! I’m exhausted by it!
Please tell me you can and do poop again ?
Appreciate any advice pls (I also have fibromyalgia)
Thanks
