There's a fine line between being there for someone, and being there too much. I had a friend who became very concerned with me, and it put unnecessary pressure on me, when what I needed most was a little space to work out my issues. Granted, I was already seeing a counselor, so I had the lifeline in case things got bad, but that was enough. All I needed was to know that somebody would be there if I needed them, not that they were always there.
