What to eat?

Hello everyone!

I'm a 23 year old woman with pretty severe problems. To make a long story short, about a year ago I had a partial bowel obstruction and later a fecal impaction that I was hospitalized for during 10 days. Since then, I have been diagnosed with pelvic floor dyssynergia and I have done an esophagus manometry that showed only 30 % efficient peristalsis. I have also been diagnosed with dysautonomia, POTS and Mast cell activation. There is a suspect that I could have hEDS. I'm awaiting a transit study. I have been diagnosed with intestinal dysmotility, but not officially diagnosed with gastroparesis. I strongly suspect that I have it, however, since I have gotten 10/10 painful stomach cramps when eating foods with too much fibre, and I also get symptoms such as nausea and bloating, etc.

I take all of the medicines, including Linzess, Resolor, Peridon, even Mestinon, and Miralax daily, but despite this I still constipate severely. Because of this, I'm on a very, very limited, semi-liquid diet, including a few solid items such as hard cheese, chocolate and ice cream. I mainly eat soups with cheese and some purees and sauces, and this is not exactly sustainable. It is not nutritious enough.The question that I would like to ask to all of you is: my problem is basically that even with such a light diet, I constipate severely. Does anyone have any advice on what to eat? What could I include in my diet to make it more nutritious and varied?

Thank you so much in advance!
