Afirmations are sayings we repeat to ourselves that we wish to be true it can really have an impact on our emotions and how we ourselves feel—the meaning of affirmation is to steady and strengthen—
Some you could use are:

“ I love myself, my body and I look after and cherish my body for all it does for me”
“ I can control my thoughts and emotions”
“ I believe it will happen and it will I have strength and an inner belief”
“I now free myself from destructive fears and doubts”- (Louise Hay)
