Tell yourself that the sort of parent you have is not your fault. You didn’t bring them up and their behaviour is their responsibility not yours. Nor will you be able to change them.
What you can do is try to help yourself so here are some suggestions:
1. Build Up Your Self Confidence
Write down three things you are good at. These can be anything from remembering football scores to sewing.
Think of three kind things you have done recently for a friend, a relative or an animal. No matter how small or insignificant you think they are.
Write down three good things about yourself.
Use what you have written to help convince yourself that you are NOT like your horrid parent and that you deserve to be loved.
Try to get enough sleep.
Eat as healthily as you can.
Talk regular exercise such as walking.
Keep in contact with your friends and see them regularly. .
Make time to enjoy a leisure activity.
3. Try To Manage Yourself Better When You Are Around Your Horrid Parent
Write down one thing that you have done to help yourself this past year when your horrid parent has tried to undermine. This might be something that you planned to do, or that you actually did. What did it feel like? How effective was it? Could you try it again? Could you try something else? What do you need to find the courage to keep trying?
If you have found something helpful, keep thinking about it to help you feel better.
Remember that you are not alone - sadly many other people will have similar experiences to your own.
