Trying to think positive

I'm trying my very best to think positive.
I'm trying my best to take things easy and not hard on myself
I'm trying my best not to think bad /hurtful thing in my past
I'm trying my best not to think of negative things
I try to talk/think positively
I try to sing more

Avoid negative thoughts
Avoid thinking of the past (people who hurt me)
Avoid mixing around with friends' who gossip .

Dear God , please help me able to do the above things!!!
