Doubting every letter of my type.

I just need some major help, and I need some direction. I have reconsidered EVERY letter of my type, and I will just not be able to be sure that any type is actually my type.

Ask any question, and I will answer it.
Thanks.

lmao. Calm down! (I yell hysterically) :)

It's okay, we all use all the functions. It's about preference what comes first to your mind.

Just ask yourself about the last time you made a decision. What decision did you make? Why did you decide that? How did you decide that?
Why don't you illustrate as many steps of your decision making process and if you post one then we can tell you what function you were using.

I think Im Infj. I just spent this whole time from 12, looking for it.
Btw, the last time I made a decision was getting on this computer, especially this late at night, while knowing that if I got caught, I would get into trouble.

I believe that is the feeling function, instead of the perceiving function.

For the introvert/extravert questions, try just comparing best case scenarios to remove any social anxiety or fear of being alone you might have. For example, would you feel more fulfilled and energized going to a party where everyone liked you and accepted you or spending time by yourself doing something you really love to do? Would you rather work on a project with a group of enthusiastic, friendly teammates who valued your contribution and didn't play politics, or would you rather work on it by yourself, without outside distractions? Also, try to remember the best times you've had with a group of people and the best times alone or with one or two others, doing fairly similar things in both cases. Which ones were better?
