It's so horrible.. I had to get up at 4am last night because I was having what felt like a panic attack, I ended up having to sit on the toilet for more than 30 minutes and even after that I still did not feel relieved. I've already been to the toilet 3 times today and am still having stomach aches from diarrhoea... it has such a big impact on my life. I can't even leave the house without having a panic attack and a massive stomach ache. I've had this for years. Anyone else experiencing this?
