Dear Anne,
I usually use this for rookies and new members but I'll remind you:

You are not alone.
You are one of us.
And we are here to help.

Granted, opposite sides of the planet and time differences, but we are always here.

Now, your sister.
No matter how it may hurt to do it, cut her loose.
I know, I know. And I'm not saying it to be a jerk. It may hurt to put and keep your distance from her, but what she's doing right now is already hurting you.

When people like that do those things, I push them to arm's length and keep them their. (Not within arm's reach, mind you.) And when it's someone I care about or even loved, it hurts to retaliate that way.

But I have a limit to the pushing I will tolerate before I push back. And as you said, it get's bottled up only to build into an explosion. (I used to be that way. Not so much anymore). But when that happens, I'd hurt myself and the other person without resolving the issue. Not healthy for anyone involved.

Effexor. Yep. We got it here. Tried it years ago for the depression and OCD. Didn't see much on results so I went back to Paxil. But that's just me.

I wish you the best, beautiful.x2
