my psychiatrist once pointed out that, in a way, panic attacks are 'psychotic' in that you lost touch with reality momentarily (e.g., believe you're dying). I once 'saw' blood seeping into my eyes and 'knew' my brain was leaking, causing me to totally freak out for about 30 minutes until a friend brought me back down. But I was told that this wasn't considered a 'true' psychotic episode because it wasn't a sustained idea/narrative...like people following me, controlling my mind etc. It more in the panic-attack 'family.' I also used to worry people were poisoning me or slipping me drugs, but not enough to not eat/accuse them. In other words, the thoughts crossed my mind and I considered the possibility, but was able to talk myself out of it, even if there was some residual 'what ifs'/paranoid thoughts. I remember these being described as "pseudo-delusions."

I guess my point is that there are lots of semi/psuedo/sort-of versions of 'psychosis', if you define it as a loss of touch with reality, but I personally wouldn't say I've ever been psychotic because I was able to 're-connect' with reality pretty quickly. Anxiety and depression can seriously distort how you think and perceive the world...you can't think straight or sleep or interact normally and that can make anyone feel like they're losing touch, but the fact you can recognize that you don't feel right, at least to me, is a good sign you aren't experiencing 'true' psychosis.
