Yep. I think this is a state that all feelers should be able to relate to

Thinkers have to work through being able to accept and show their feelings for other people, be nice and cooperative to others without throwing up

(i'm over-exaggerating of course). Feelers have to work through making competition or where you have to be mean to other people more acceptable to themselves.
For INFJs, our Fe and Ti are like in perpetual conflict but Fe usually wins out and tells the INFJ that competition is this distasteful unpleasant thing. It is alike thinkers' logic function telling them that emotions are just so repulsive. So when faced with competition we might have to withdraw and process it first (and thinkers of course have to withdraw to process their feelings). This conflict is a bit exacerbated by having Fe and Ti close to each other in functional ladder. In think MBTI types with dominant feeling function and inferior thinking, or dominant thinking and inferior feeling experience this type of internal antagonism less often just because their inferior function rarely comes in conflict with their dominant one. It is more alike their blindspot that only sometimes acts out for them. I don't think they pay as much attention to it as INxJ and ENxP types end up paying.
Whenever I started to develop my Ti more it has ganged up with my Ni and learned to trick my Fe into accepting competition. Through Ni function I have observed that there are people who really seem to enjoy being competitive. Not only that, but they also understand better and respect more other people who are also competitive and are likely to judge you negatively if you 'irrationally' opt out of competition. This is especially true when you are in company of T-types. T-types naturally like instances where people compete - why men one-up each other in conversation, like watching sports or action movies, or playing first person shooter games - most of them are Ts actually. Observing competitive interaction or participating themselves in it actually releases feel good chemicals in their brains. So then if I am competing against somebody like that I don't feel like it is wrong somehow.
But yes all instances of competition have to pass through my Fe filter and if I feel that they are improper somehow then I do not engage (and a Ni filter, of course, that points out that some competition is just useless and meaningless).
