One of the most important coping strategies is to manage expectations, to learn to roll with the punches, and to adjust your mindset.
My best day is someone else's worst nightmare. On the flip side, my worst day is someone else's best day.
The more days that I can see as 'good days', the more those days are cherished.
If I have a string of bad days... If I adjust my mindset and make the decision that, for now, this is my 'new normal', all of a sudden, those days don't seem so bad after all. Then if I have a couple of worse days, it's not so drastic, and when I start to have BETTER days, they will seem like a blessing.
Every single person's life is full of ups and downs. If we can manage how we see our lives by making our 'downs' look like 'ups' and out 'ups' look like miracle days, then that's a lot more happiness coming out of the mix.
Adjusting your mindset into knowing that certain things are temporary, that one can truly learn to live with anything, and that having a 'good day' is a blessing and should be cherished - even if that good day used to be your absolute worst day imaginable in the past. Being able to see things differently helps. It takes time - it takes dedication - and it takes practice, just like any other behaviour or habit.
Adjusting your mindset is half the battle in taking control of your life and not allowing chronic illness to dictate what you can and cannot accomplish.
