Thanks Janis, i appreciate it.
Thankfully, i'm finally feeling better, after about a month of constantly feeling awful. It's still not great, but it's back to being fairly manageable. And my dad's actually been around more at last, so i'm feeling less concerned about it.
I need to go see my doctor, and review what's going on, get them to try and finally figure it out, but i'm back to a positive headspace, after having a bit of a wobble. Weeks on end of feeling rough every day have this way of wearing down your resolve and leaving you grumpy and pessimistic. I was just getting a bit overwhelmed by how sick i'd felt for so long.
