Is this paranoia?

[minerva]

What is paranoia? I have thoughts/feelings all the time that people are watching me and judging me, saying bad things about me, I feel like someone is going to find out that I don't deserve to be alive and some "authority" is going to confront me and make things much worse for me.
Is this just my own negative feelings being "projected"? I don't even want to leave my apartment most of the time because I don't want people watching me and judging me, even though I'm not doing anything "wrong".
I don't hear "voices", just thoughts and strong feelings. Even when I'm in my apartment I feel like I'm being watched and judged.
