i'm sorry you're feeling that way... i'm a little worried, sweets, especially because hiding how you feel and what you're doing during the day can't be helping those feelings of anxiety you're describing.
can you "come clean" to hubby? let him in on a little of this anxiety you've been feeling? should you talk to your doc about going back on the meds? i know sometimes people are off of those types of meds and do fine for a little while then end up back on..... do you think they'd help you?
i'm confident that the hypno will help you with the IBS stuff, but it sounds like you've got more anxiety going on there, not just the IBS stuff...
anyway, keep talking when you need us. we're here! hope it all gets better soon.
