Scared of confrontation

I have some deep rooted problems with coming forward and being completely honest about my feelings. I tend to let things fester in the pit of my stomach and eventually it blows up or becomes some deeper issue. I’ve lost friendships due to me confessing about issues in relationships. I can think logically and I can identify what I need to do objectively but when I add my emotions to the equation it seems impossible to do anything. Does this make sense? Am I rambling? Can anyone at all relate?
