A lot of amazing technical advise, but I'm going to give the other type. Do you live with anyone or have someone in your life that you might not have parted on good terms with that had access to your devices? I've seen a "supportive spouse" sabotaging their significant other to take control. Security is often about a technical quirk, but you might need to look at the people around you. It sucks, but sometimes its the problem.
