Why does this feel so right but I know it's so wrong?

That all depends on what "this" is. It may actually be right for you, and wrong by someone else's standards that you have had imposed on you. If everyone is consenting, and nobody is in danger, you shouldn't worry so much about whether it is right or wrong for anyone but you.

It feels so right because it gives pleasure. You know it's wrong because your morals are higher than the task you are doing. :)

Sometimes being in love with somebody feels right, no matter how, when or why it happened. It doesn't mean you should continue, but it doesn't mean that you have to stop either. You have to make the decision based on your own ideas of it.

As for what the "this" is, I like to think it feels right because it brings a relief of some kind .

This is a battle of the heart and the mind and has baffled so many people since the beginning of man. In situations like this, it is best to make a pro's and con's list and compare not based solely on the number on each side, but the amount importance of each and how they affect your life.

It depends on what you're talking about. If you're talking about your sexuality just remember that there is not a wrong one.

Everyone is addicted to something that takes away the pain. Find something healthy that takes away that pain. Music is good for that.

because you in that state of mind where everything seem to be right, omniscience, theres no other smarter

You are the expert on you and your situation. You get to decide for yourself what the definitions of 'right' and 'wrong' are, what counts as being 'right' or 'wrong'. No one else is allowed to tell you what is right and wrong. It is okay to ask for others opinions on what is right or wrong, but ultimately we get to make those decisions for ourselves. Almost all choices have consequences either way, and we get to choose which consequence we are okay with and which one we aren't, and whatever we decide will be okay for us. Always do what is best for your own healthy well-being.
