hello there, can i start a sentence directly with verb?
For an example : cheer(verb) me when i sad.


besides that, should i put "s" after cheer? Eg:"cheers"

thank you..

Yes. They are called imperative verbs. For example,

Cheer me up!
Sit there.
Eat some cake.
Walk the dog.
Move over, please.

With imperative verbs the subject is covert (You):

(You) Cheer me up!
(You) Sit there.
(You) Eat some cake.

The subject is a 2nd person singular pronoun (i.e., You), so -s is not required. -s is required only with 3rd person singular pronouns,

He cheers me up.
She sits here.
It eats.
