I am really sympathy towards you for not being able to pass even after 3 years

[Learning_English]

My friend failed for three consecutive years. So I went over to him and said, "I am really sympathy towards you for not being able to pass even after 3 years", just to sneer him.

Do you think the expression in quotes is correct. If not, please give me correct expressions.

Well, in any case, it is not very nice, but here is a corrected version:

I am really sympathetic towards you for not being able to pass even after 3 years.
