Start with routines. I'm a great believer in routines. Everything is routine. Sounds boring but it gives me the stability I need.
It took years to establish what suits me and my family.
To give you some examples:
I always run on Sunday mornings. You could do a DVD/youtube exercise.
Saturday night is pizza night.
In the summer we spend our time outside, as in we don't decorate/DIY, do nothing to the house, all that is for the autumn/winter.
Save 12%of your income into a holiday fund. Every month, 12% goes in a specific pot. Pay yourself the 13th salary as it were, and book a holiday. It doesn't have to be Orlando Florida.
Forget about instant gratification. You'll get more satisfaction if you wait a bit. So if you need, say, a bicycle, save the amount you need, every month. Doesn't matter if you have the money right now. You never know what might crop up. So £25 a month on the side and by January sales etc you get the gist.
Another thing that works is: make a decision and stick to it. It might not be the perfect decision, but it was/is the best at that specific time, end of.
Label your emotions. Say it loud: I am bored. I am at a loss. I am happy. I am angry. Etc.
Be grateful. For 1-2little things each day. This morning i'm grateful for my nice china mug and the really nice coffee in it.
Give hugs. To your children, friends, family etc. Being phisically close to others makes us happy.
Ask for help when you need it. :)
