Have I been blocked on facebook?

[Loverboy]

I was searching for a friend. First few tries, she did not appear. After a while, she did, so I clicked her name but I was redirected back to home page. I tried again but the same thing happened. I then went to a mutual friend's profile to find a post I made on her wall a few months back. I remember that the person I suspect who has possibly blocked me leaving a comment on my post before but now I cannot see the said comment anymore. Also, I saw one of my comments on that wherein I have tagged her. Now, her name is unclickable. The last thing I checked was if I can find her through mutual friends, and I couldn't. Nor can I find through google or through a fake account. Help please?
