I understand your concerns. I was off the site for a few months because it a) made me sad/envious when I saw other people in R while I was in limbo, b) made me trigger at times, and c) forced me to see things I wasn't ready to deal with.
However, I come back when I need the support or feel strong enough to offer support to others. In fact, I've been quite active here over the past couple of weeks.
This is the only place I can turn to that is filled with people who really know what I'm going through. No one is here to judge me.
I think it's healthy to vent and to connect with people who can understand your pain. As long as it doesn't take you away from your responsibilities (family, work, etc.), you're doing fine
