The "staring" thing was a challenging ANT that I had to deal with when I was really struggling with social anxiety...as I got better, I started to realize little by little that a lot of the time, there will be people who look at you, but they are in fact not usually harboring any judgement or anything toward you...sometimes they are just curious or it just so happens that they are looking at you (or in your general direction).
In your case, I can't say for certain but it sounds like it's more of the curiosity thing going on. If you really don't like the other people in your country, then it's likely that people will be looking at you.
The good thing is that this is something that you can overcome, as from my experience, I am able to be more rational about when people look at me, even if I feel they are staring at me. For now, if the negative feelings are really strong when people are looking at you, I would suggest using some sort of distraction to take your mind off of it. Listening to good music (and maybe even humming along to it) is a good distraction when you are in public...I used to listen to my headphones in the grocery store when I was having a bad day and the ANTs were trying to convince me that everyone was staring at me. I understand that listening to music cannot be done all the time, but it is still a good distraction to use whenever it can be used. This strategy is helpful to deal with the negative feelings that you are experiencing when people look at you, as it will get your mind off the anxiety and negative thinking when you are around other people.
Another good strategy is to turn the tables on the ANTs. For your situation, saying something like "Maybe it's not as big of a deal as I making this out to be, maybe I do not need to worry about if people are looking at me and maybe I can be more comfortable with myself so if people really are looking at me for some reason, it won't affect me like it used to". Statements like these will help prepare your brain to open up to the fact that you don't have to feel anxious about other people looking at you, and so naturally, the negative thinking and feelings you have regarding it will begin to diminish.
Hope that helps.
