Thanks everyone! I think you're totally right, MusicLover82; it's absolutely larger than an 'episode'. I did talk about this with my T when I was seeing her, but I honestly can't remember what she said about it and whether she offered any advice or not. I'm sure she did, but we were also working on more practical stuff for my life at the time.
So, I had a great dinner with my kids, watched a cooking show with them online before their bedtime, had a couple small glasses of wine, and went to bed. I slept in today, then had a busy morning (including exercise!), and went to a local festival with kids & puppy. All in all, I'm feeling pretty good, except when I think about that post. It really just hits one of my buttons, I guess. I don't know if it's worth trying to get back in with my T or not. At some point, I really need to let go of the fact that I don't have a close relationship with my siblings, despite them having a close relationship with each other. Looking forward to thinking of something fun to do with the kids again tonight, instead of perseverating on this (I hope!). Avoiding problems is a healthy way of doing things, right?
