Don’t be to hard on yourself. It is understandable that you suffer anxiety based on the experiences that you have previously had.
It would almost be more worrying if you felt no anxiety at al.
Its a good thing (in my opinion) to maintain an awareness of what could happen again, there are no guarantees that it won’t. Maintaining the awareness however doesn’t mean it should consume your life as we are also aware that that we cannot control the actions of others.
The anxiety, distrust etc has been built up over time and does not go away as soon as a recovery appears on the horizon. I too would have had the exact same thought on reading such a message as much as I wouldn’t have wanted to ! even I think if several years had passed – it doesn’t mean there is anything wrong with you.
