Intense Stare/Difficult to Make Eye Contact

Not quite sure if this is the right place for this topic, but the title tells most of the story on why I've come here.

I have had trouble making eye contact with others since high school (14-15 yrs old) I'm 27 now and it's getting pretty bad. I have to give presentations daily for my job and I'm constantly told to make more eye contact. I'm not really afraid of other people, and to be honest I just can't stand being around others. Most of the time when I am around other people I am generally disinterested in what they are saying or doing and I look for reasons to hate whoever is in front of me.

I'm afraid that if I make eye contact with others for too long they will pick up on that inner hatred. I can immediately tell that I make other people uncomfortable just by making eye contact while talking to them about basic things. I have basically trained myself not to make eye contact because of this.

Has anyone experienced anything like this?

I have.And believe me,I tried my hardest to make it better.The problem is,now everytime I make eye contact,I either stare at them with a RBF or either a funny thing about being in this kind of situation keeps tickling me and it makes it worse,because I both have to keep myself from smiling too much and not staring hard like I hate that person i'm making eye contacts with!
