stomach sickness

i went to doctor today and he gave me lots of pills. i could just have some IBD, noone knows. and a long list of medical tests to go and check. 

i also have to eat my meals regularly and improve my sleep routine. and no sweets. a lot of meals i eat are pretty sweet and i have sensory issues what do i do? i want to feel better already. and i'll try to go ride a bike once a couple days... we'll see.
