Is this Happening?

Like a gut feeling that makes you notice things that were not there before. I have spoken to very few people about this, obviously, the "Someone is following me" thing at first glance sounds crazy, especially to me. I am a single Mom to a beautiful little girl. Up until about a year ago (when a psycotic stalker fixated on me)I led a quiet life. Since then I have slowly digested unwillingly that I am being followed...of course who wants to think they are paranoid??? There is enough going on in my life that I pretended not to notice, but at this point knowing certain faces, cars, lic plates, patterns, sounds when I pick up the phone or cars beeping out what seems like codes whenever I leave or arrive somewhere, people making themselves obvious as they try to not be. Cars making u-turns behind me or pulled over to the side waiting for me to pass then following me, I could go on and on. Believe me I am the sanest person I know and I would love the luxury to just cal it crazy. But unfortunately It is my truth. It is a horrible way to live. It IS starting to make me feel paranoid,,,I feel like I have virtually no privacy even in my apartment. I hear weird sounds and my cat freaks out and growls at the door or at a random spot, She never DID THAT BEFORE...I do not know what to look for......People take pictures of me all the time. I am not a celebrity nor do I look like one. What worries me most is the privacy invasion of my child and the many pictures that have been accidentally taken of her (then the person pretends to take a picture of something random , like a McDonalds sign or an empty resteraunt table) its almost too obvious. Is that a tactic of some sort??? I have been pretty strong through this and have as of yet to find a way to prove any of this. there are a couple of people that would go to these lengths (my ex is an option, so is the stalker) The stalker threatened this exact thing but I dismissed it, until I couldn't anymore. I have even had a couple people elude to it. Then there was the guy with a truck full of high tech camera equipment who was zig zagging down small streets and I cut him off and ran up to his car cause I was so pissed and he stuttered and turned red and said he was a celebrity photographer and he thought he saw someone. What is going on, has this happened to anyone? What would make people so interested in my comings & goings for such a length of time, how can I counter this or prove it in some way?? Ive taken pictures of the same cars over and over in different parts of Calif. but who is going to do anything about that? They will just say it is a coincidence. I do have a lawsuit going on with the CHP and another with my ex for custody) I am at the point of putting up a sign in my car offering 500 dollars for information so that I can prove that this is or isnt happening.

Money is the one thing that people cannot resist. Could someone have made a false allegation against me? How do I find out? Wish me luck, or send advice..thanks
