You give us a stupid ton of information and don´t even know what you want. Then you don´t even tell you if you´re male or female. I guess you´re a women.

I am really lost here it is so complicated that idk what's going on.

No, you make it complicated. Start to work out! That´s really all.

First of all I'm gonna say I'm a person that deals with a lot of stress. Also I don't have a stable and good sleeping pattern atm.

You need to change this if you want to make a change. This is way more important than you think.

a friend of mine did this test for tolerance in foods

This is indeed fucking nonsense. Don´t eat pasta, whole breads and dark meat and every other high calorie food and you will loose weight.

if there is something wrong with me or I'm just not doing the combination of things I need to do well to lose weight.

There´s nothing wrong with you. You don´t eat less calories then you consume.

fat on my arms

You can´t loose fat on specific areas.

You really making this more complicated then it is. Start to go to the gym or do any other sport, learn abit about dieting and alot of your problems may go away. Also be patient. You can´t change this overnight.
