Is writing a poem to my crush a good way to express my feelings to her or is it to cheesy?

Definitely. It gives you good experience for when you want to move onto writing novels. I used to do similar, but now I'm just focused on writing novels.

But yes - it is great to practice writing in different forms, even as an outlet for emotions.

Yes and no. Simply expressing yourself sounds like you just free form it. Random thoughts on paper for the purpose of .

. . .

What exactly? This is like making random marks on paper and calling it "expression." At some point you have to take the pile of ideas and mold them in to something constructive.

THAT is expressing yourself.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
