Hi the anxious mind,sorry to hear about your difficulties.
I actually think my anxiety has improved since having my two boys. I think it's because you are so busy looking after them and you love them so much you don't have as much time to notice how you feel!
I think before they were born I had more time to myself so naturally I would notice how my body was feeling etc. I had six years of being a single parent too which I really thought would be dreadful but the same thing applied as above. I did still have symptoms but as I was so busy I had no choice but to think of other things which actually helped. I didn't try and MAKE myself think of other things I just had no option! That's a few years ago now and I am a lot better apart from some occasional health anxiety!
Hope this helps.Take care
