Fair enough, it happens.

Can you give me some advice, there's this girl I like who is well two years older than me and I love her very much but just can't say it to her or anyone else and I was very depressed about it last weekend so see what you can do. And we'll you see I only got a few weeks to tell her I love her and after that I'll probably never gonna see her again.

Well, as random as it is. Girls love confidence. Just frantically tell her in a very romantic and casually random way. Have a sort of speech ready, let her know you care about her. Only do this if you two are good friends. Girls love to stuff like that.
