Should I tag my crush in a "tag your crush" post on Instagram?

I want my crush to know that I like her but I'm super nervous and I don't want her friends and the whole school to find out. I'm scared she'll ignore it, block me, or think I'm creepy. Plus my annoying younger brothers will give me s**t about it since they have instagrams too.
