Congrats on making it through the weekend.
I'm a SI too, or used to be....or still am....you know what i mean.
My last episode was a few months back when i was sooo stressed out. Working nights and taking care of DS during the day has me rolling on 2 hours of sleep a day, so I feel your pain. I did regress and now I feel crappy because I'm trying to fade the scars out before DS can get old enough to ask what they are.
I was given the suggestion to write, and it seems to work for a lot of people, so you can try that out. I'm far too hyper for that, so going outside, taking DS to the park, cranking up the music and dancing through the house all work for me. Anything to get that nervous engery and that urge out and the adrenaline in. I was in Tae Kwon Do, so practicing that helps out a lot, plus DS is picking up on it as well. If its REALLY bad, my doc gave me Atavan(or Adavan? O_o) and I'll take a half tablet to calm my nerves.
I saw you said your husband doesn't know how you feel. Talk to him, it can work wonrders if he's easy to communicate with. My DH sometimes gets on my nerves, if I'm stressed, he asks if I feel like hurting myself, but at least I know he cares. So talking to him or anyone else can do the trick as well.
