Hey there, always have hope. I have been in your place exactly, and after 26 years I have found what works for me.You need to find what works for you, now with the internet and forums like this you will find your cure believe me!!!! Often the smallest changes can have the biggest effects. I would suggest staying of gluten, diary products and animals flesh, ie go vegie for a week, sip lots of water but not whilst you eat, when you eat take a digestive enzyme tablet, and have a little apple cider vinegar, see if that works. If it doesn't we can tick it off and then try something else until we find your cure :). Have a positive mental attitude, expect to find your cure and have the life you deserve, good times ahead!!!
Let me know how you do :)!!!
