I'm not sure where to ask this question. I have an old friend that lives out of state. He wants to visit me for a day or two this fall. Last year I made an excuse to avoid seeing him, because it caused me so much stress.

About 5 years ago, I flew to meet him for a weekend. We drank and laughed and did some tourist stuff. Long story short, when I arrived home afterwards I started having psychosis. I can't explain exactly what I believed, because it kept morphing. In general, I believed that evil forces were oppressing me and that my friend was either part of this conspiracy or under their control.

I saw him six months after the psychosis started, but at that time I thought that God would protect me from harm. Now I am mostly an atheist, so I feel nobody will protect me except me.

So here are some concerns I have about my friend. Many of them may be delusions, but they are still concerns in decreasing order of reality:

(1) I gave up drinking and our main activity together in the past was always drinking.

(2) I think he is bisexual and attracted to me even though I am heterosexual.

(3) I suspect he drugged me to trigger the psychosis and I think he tried to drug me again when he visited six months later.

(4) I worry that he has magical powers because it seems like weird coincidences happen when he is visiting - almost like he can control events somewhat.

He is a good friend and I hate to treat him shabbily by avoiding him. On the other hand, I have so many suspicions that I dread spending time with him.

Any suggestions?
