feelings?

For most of my life, I have heard people say, “Feelings cannot be trusted”. And I must have said it a few times myself. I assume that feelings are subjective and therefore not trustworthy. But “reason” (whatever that may be) can be trusted because it is objective.

Why? Why can I not trust my feelings? Why can I not trust the subjective? In fact, why would I trust the objective? And is there such a thing as objective? Is reason always objective?

Why is only that trustworthy which is outside of me?

Maybe Boethius is to blame? Most likely it is me.
