I'm not sure if this is totally relevant to the topic, but when I'm assuming that something will go badly (the big one for me was assuming I was losing my DS when I lost his twin) and I was telling myself that I'd lost another baby and that therefore I'd never have a child etc etc, I eventually decided that dwelling on those thoughts wouldn't make it any easier on me if it did turn out that I'd lost him. Like, I wouldn't go ''oh I was right all along, hooray!''

So now I try and hold onto hope, I decided I'd never regret hope, never put myself down for believing in something even if it turned out badly. I have no idea if it actually makes any difference to the outcome, but it definately makes a difference to my mental health.
