Mindfulness and using the jar coping skill is very helpful.

Jar coping ... Its really about writing down on slips of paper what is good in you and your life. It can be hard to start with, I asked my husband or people I know for things from there point of view..

Examples:

I have great hair
I always am around if someone needs to talk.
My home is always in order.
I am pretty ( tough one for me)
I love to read novels.. Maybe re reading one ,
When was the last time I did something just for me, have a fancy cupcake ?

Any way...you can also goggle ideas..

So when your having a day or a week that your feeling like a useless lump of whatever , Pull out a slip.. Sure you might not believe it at that moment .. But it just might help out a bit
