Not sure what’s wrong??

So recently I have absolutely no appetite or desire to eat at all and every time I eat, no matter what it is, I get really uncomfortably bloated and really can’t finish meals. It’s been happening for about a month and I’ve lost weight and feel kinda crappy in myself and moody all the time. If anyone has any ideas I’d be grateful because it makes getting up in the morning and being functional at college quite difficult. Thanks! (I know it doesn’t look much in the picture but this is a lot for me and it had gone down a bit already)
