A Little Riddle

I am not a motivator, but I can stack you up some confidence.

I am not charming, but I can get your full attention sometimes.

I am not a comedian, but I can pull out some jokes and laughs.

I am not intellectual, but I have the answers to some of your problems.

I am not a consultant, but you can always come to me and talk about your life.

I am not a first aid kit, but I can heal your wounds sometimes.

I am not a policeman, but I'll try to help you as if it's my duty.

I might not be your shoes, but I come along with every step you take.

I might not be your fans, but I support you with every choice you make.

Who am I?

I'm your best friend, standing here just for you.
