Yes my experience tells me that time does heal it, but it requires emotional work.

She's her own woman and you should listen to her and your friends. We are all just human and none of us are perfect. You don't sound like the kind of person who would hurt people they love on purpose.

What helps me is to take time away from work and hobbies and the dopamine hits. I go out the door and follow my intuition, not my mind. Then I find a place to stand or to sit and I stay there for as long as I am able to be patient. It has never failed to help me.

Sometimes you just have to wake up and look at the ceiling for a while. And to be brave enough to face your feelings, by directly experiencing them. The only way I can make it go away is by respecting it and giving it the space it asks for within me. That is, I allow myself to feel guilt, or shame, or fear. That's when it melts away and I can find what I've been looking for.
