Hello Britt
Sorry you are having a rough day.
What kind of investigations have you had, and did you see a GI specialist?
Regarding the fibre supplements you are taking ---are they soluble fibre like oat bran, psyllium, prune juice etc?
You do need to take plenty of fluids with fibre.
Were you diagnosed with irritable bowel? Many people find this to be an unsatisfactory diagnosis but current thoughts are that is may be a precursor to IBD such as crohn's.
If your diagnosis is IBD then you should be under a GI specialist.
Meantime it might help to reduce the fibre to a level comfortable to you, start slowly and gradually increase to a tolerable level and drink lots of water or fluids while taking it.
It may help your day even now to do this.
Feel better soon
Hugs and best wishes
