Dizzy after eating?

Ive been eating 3 meals a day like my doctor told me to but today I ate in n out ( fast food burger & fries for those not familiar) after I ate that I started feeling a bit dizzy so I got kind of anxious but anyways could this have been bc it was salty & just too much fats ? Im worrying right now about this. When I eat when my mom cooks or foods that just isnt fast food I feel fine. Also I ate a chocolate before I ate in n out ive noticed before when I eat too much sugars I feel dizzy. Got blood tests done last week but getting my results until Monday, the doctors didnt call early tho so my mom is saying Im fine but I dont know ugh. Dizziness is now my main concern of my anxiety 

It seems like your dizziness is caused by a spike in blood sugar levels.  When I eat greasy or sweet foods, I get anxious as well.  

I would recommend to look up "Glycemic Index Food List" on google.  Glycemic index shows how fast different foods give you a spike in blood sugar levels.  The lower the GI, the less the spike is, which will give you sustained energy, instead of an instant energy causing anxiety.

It has helped me with anxiety.  

God Bless you and your journey Stacey!

Thank you Gerard I will look into that, god bless too !
