What is the easiest way to ignore her?

Well, I agree if it was like once a day. But it's like every 5 minutes.

The only way you could know she's looking at you is for you to be looking at her. If you're looking at her every five minutes, then maybe you need to reconsider your statement that, "I'm not really interested in her."

Well, it is not what you think. It is just like I'm the kind of person who likes looking around a lot not for a particular reason.

Your question isn't about "looking around" it's about "Eye Contact." Eye contact is when the two of you are looking at each other. It takes two sets of eyes.

I'm obsessed because she made me paranoid, everyplace I go I feel like I'm in a shell and she is like watching every move I make.

The thing is it's easy to mistake repeated eye contact for interest, so if you keep looking at her you're probably sending mixed signals and dragging this thing out far longer than it needs to go.

She didn't "make" you paranoid. No one can "make" us feel anything. We have to own our feelings. You haven't indicated that she has any intentions to cause you bodily harm, so most of this is likely in your head. Let's put this in perspective... this may seem huge now, but 1, 2, 5 years from now, you aren't going to remember this. Live longer, and you'll have real problems and you'll know things like this aren't worth the energy.

I'm going to try to take the same advice. Look, I'm obsessing over lots in my life right now, too. We both need to breathe, chill, and relax.

If you stop looking at her, she'll likely lose interest as well.
