BLOATING PROBLEMS !!!!!!

I bloat every time I eat, no matter how much I eat & I've been like this forever!  I could eat a 3 course meal or just a medium mc donalds fries & I would bloat the exact same, everytime.  Eating less doesn't help. I have no idea how to stop this, I feel like I can't go out!  I go from being so thin to looking sort of pregnant. 
Are there different foods I can eat?  Does anyone else have this as bad as me (I ate 1 scone & small slice of cake between these photos)?  How can I get rid of this?  
I've been told it may be water I've not drunk much.  My belly feels like a bubble, it isn't fat, it has kind of inflated !!!!
