Last night when entering my apartment at 2am, a man was in the building by the door. I was trying to open the door and he held it so I couldn't. I tried again and he glared at me and still held it shut. He looked so creepy and I was scared to death. I turned around and saw my neighbor(he's like 6 foot 3 and very intimidating looking). He asked what was wrong and I told him so he swung the door open and gave the guy a look and the guy said hi to him. He waited until I got inside and made sure I was okay. I don't know who this creepy guy was.. he went into one of the other apartments. This triggered my paranoia. I laid in bed.. wondering if he would come kill me. I was also thinking it was a planned out operation and he had been waiting for me but saw a car pull up and changed his plan.
I am still scared today. I am worrying about everything and I can feel myself slipping into a paranoid episode again. I want to stop it and I don't know how. Any ideas??? I talked to a friend this morning and that helped slightly but not much.
I saw a group of 10 people walking down my street today. I assumed they were all having a meeting about how to eliminate me.
I'll try to briefly explain my delusions:
Thinking my fiance is lying to me about any random thing. Most of these thoughts are outlandish and stupid. I feel badly that I do this to him because he's very understanding of my disordered thinking but after a week of this he's had enough and I completely understand why. :/
Thinking my future in-laws are talking about me and plotting against me. I even hear it sometimes or feel like they're reading my thoughts. This is a pretty prominent one and it forces me to be silent and not speak to them. I even cry about it sometimes because I think they're being so mean to me. Sometimes they are, honestly, but it's also part of my delusions.
Suspecting my Mom has been drinking or doing drugs or smoking. Also has been some truth to this but I go overboard.
I'm scared as I'm writing this because I think my in-laws may be spying on my computer with some sort of program or something.
I suspect someone changes the tires on my car at night when I sleep. I'm not sure what the purpose of this would be..maybe just to drive me insane.
Sometimes when getting in my car, I feel a warm sensation on the seat and I think someone has been driving it while I was inside my house. I should also point out that I'm the only person that has the keys to it.
I'm very afraid of my loved one dying and sometimes thing.. "If I don't do this task, they'll die."
I also feel as though I need to sit in a certain position while phoning someone. If I'm not in that position, then they will not pick up. I've proved this to be true.
I think military men are on the roofs of houses and building at night and they're ready to shoot me with their rifles at any moment.
I feel a "presence" behind me at night. I feel followed. It's so frightening.

I have these delusions on and off even in my "normal" life... but they hardly affect me. They really really affect me when I'm having an episode of paranoia. Can anyone help me?
Please don't suggest meds or a therapist. I tried a therapist and it didn't go well, and I have no money for another. I am also anti-med. I just want to calm down an stop it and I don't know how. I'm always open to the idea that I'm imagining these things. They are just so scary that I can't be 100% sure that I'm wrong.
