This is not easy, and you need to be compassionate towards yourself. It is normal to have the feelings that you are having. Nearly all of us here are experiencing similar feelings. Let yourself have them. It is healthy to feel them. This is the roller coaster. Just remember that these feelings wont last forever, you will feel better.
When you are feeling down or want to contact your S, I find it best to post here, to vent, to look for support.
