High bandwidth, high cpu no access to SSH, can't even access server through DO's console access.

My server went down a few days ago and I cannot get it back up. Someone please help me. Website went down so I went into SSH to reboot. Wasn’t able to login to SSH saying connection timed out. Then tried to log on with Filezilla to see what is going on and once again connection timed out error. Went to DO to access console and sometimes it will work but most of the time it stops working and so does the digital ocean website. I then have to close all tabs and try again. What is going on here??!! When I am able to get it running all I get is error messages Firewall: TCP_IN Blocked each time with a different IP address that is not mine. I get a new message every minute. I cannot keep it running long enough to enter in a command. It freezes up and chrome sends constant messages asking to kill both pages. What do I do? I even saved a snapshot and created a whole new droplet from the snapshot but same problems with that one as well? Like I mentioned in the title I am also experiencing high bandwidth and high CPU.
