How Do I get on Facebook when its blocked on my computer?

Oh, this moved to a Facebook questions section, my bad. Go to your profile page on Facebook, and block her. You have to do it from Facebook, not messenger

Why is the computer blocking FaceBook? Is it software some company or parent placed on the computer to prevent unauthorized use or visiting unapproved sites? If so, you will have to talk to whomever installed the software because it is likely you don't own that computer. It could also be the source of your internet connection that has firewall software blocking access to external sites. Or it could be your antivirus/firewall software on the computer doing the blocking. You need to be more specific on how you are accessing the internet (wired or wireless), what anti-virus or malware blocking software is installed on your computer, and what exactly you are trying to do before anyone can be of more help.

Try this, using a hosts file is very effective

You should contact facebook again. Facebook may be blocked where you are, and there is nothing to be dome about it.
