I'm not sure I would call it traumatised but I had to do A LOT of mental preparation before getting pregnant again. And even with that preparation I would burst into tears when ever I was in my GPs office in relation to my HG, so well maybe that sounds like trauma
Personally I kind of just try to keep up the momentum of pre-pregnancy and just keep swimming and both times that momentum runs out around 22-23 weeks and I have that crisis point where it all seems to hard and another almost 20 weeks of throwing up just seems impossible to bear. I think everyone who has HG hits that crisis point at some stage, before they get pregnant, when it first hits, when it is not going away. Perhaps just knowing that what you are feeling is normal and and others have felt the same AND come out the other side will help a bit?
