Sorry, I know this isn't an AIBU. But this is my go-to board on Mumsnet; it's busy and generally really helpful.
My 16 year old has some school based anxiety. This is largely due to being in class and being afraid that she's going to rip out a fart! She sometimes feels bloated and is quite windy in general. Her diet is good overall and she's in very good health.
I have spoken to her about her anxiety, and she feels it would lessen considerably if she were to (physically) feel more comfortable. Her lessons are often rather quiet (small class sizes, and a studious bunch) which is just giving her the fear even more!
She has tried peppermint oil capsules and drinking water. This doesn't seem to help particularly.
There is definitely an element of overthinking going on, but I'd really like to help her with this. She's in an important year academically, and worrying about this is taking the focus away from her work. She's quite an anxious girl in general, which won't be helping.
If anyone could recommend something she could take, I'd be very grateful 
Thanks
