Should I tell my crush I appreciate her?

YHL6965
I want to tell my crush I really appreciate her. When I met her, I was kind of depressed and I want to tell her that I really appreciate talking with her because her company got me out of personnal problems.

Do you think she will think I'm an unstable guy or would she be touched by this? I don't plan on detailing the part about personnal problems, I just want to tell her how her company was comforting.

Thanks for all the answers ladies and gentlemen. Actually, we're both going to a party and eat together soon and I plan on telling her during the evening. I'm so excited, thanks for giving me some motivation to overcome my shyness! :)
