It's a lot to cope with, children and full time work and PD: two out of three of those does for me! Of course you feel anxious and tired - but super-so because of the PD. So PD makes you anxious, and you're anxious about your PD . ..
So first thing is to be kind to yourself, take a breather. Then, how helpful is your o/h? We rely on our carers, and the more you can work on this together the better. Others will be better qualified to talk about the kids. Next up, don't look too far ahead: mostly PD is slow-moving and there's no point in worrying about next year let alone next decade. Finally, how helpful is your employer? There are laws, you know! Oh, and other finally, keep exercising, you know it makes sense. And yet another finally, stay positive (i find that one the hardest. No, the exercise one).
And a further finally: keep posting. We're all In This Together.
That's enough finallys.That's also far too much advice. Ignore any of it you don't like.
