Issues with paranoia

I've recently been extremely paranoid now that I'm doing better mental health wise or since I'm on the path to getting better. This has caused impulsive habits such as email changes, changing to private email providers, etc. In the past I've threatened parents for believing they abused me growing up, talked to people I shouldn't have talked to, etc and I'm not sure what to do. Part of getting better is realizing that some people might believe I'm not doing better or possibly want to "track me". I've been very paranoid and have had issues with believing people are out to get me. Any advice? I'm worried because there was a state in time where I was doing horrible.
