Yup, I have a tendency to really throw myself into things and love them and do them fiercely, (not always that bad to do that either ) which I have certainly done with PC - it must be a part of both my OCD nature and my manic side!
I have a hard time doing things in moderation and keeping things balanced; I try and try (and am obsessed about trying!), but man, I catch myself immoderate and unbalanced and obsessed a lot.
That said, I think when we need to lean on the support from PC, it's OK to give ourselves permission to do that.....and when we have a need to give support because it helps to fill the aching hole within too to make connections and be helpful, it's OK to give ourselves permission to do that. Just make sure to take care first of real life things/people in our lives.....
