Sometimes, even normal people can develop issues, due to stress and other factors, that cause them to act and react irrationally. People around you can react in a negative manner to that. Others can use it to screw with your head. I would say you need to find a counselor, priest or someone you trust implicitly to help you re-establish a grounded perspective and determine what is true and what is paranoia. It may be you expressed a radical view and are in fact being investigated for something. You should not allow it to drive you over the edge. Just make sure you are more conservative in your actions, so you do not commit a crime you can be charged with.
