(Double posted from Anxiety, Panic, and Phobias)

Hey everybody. I really need your help right now because my anxiety is so strong and I'm so scared I'm actually going crazy!
I've been diagnosed with everything listed below and was never given a diagnosis of psychosis but I'm always worried I'm going to lose my mind.

Some things have happened recently that have made that fear come back really strong and I can't stop worrying!! Please help me calm down, I can't go to therapy until next month because I can't take off work!

So my OCD fear revolves around remembering things that didn't happen, therefore being delusional. The thought of this absolutely TERRIFIES me!
The other day I had a "memory" of my little sister saying she liked the blonde streaks in my hair. It felt really real...but I don't have blond highlights! I really do not think she said it but I had a fleeting memory that she did! And the worst part was it came out of NOWHERE. Just a totally random thought.
Also, yesterday I was on Pinterest and could have SWORE I saw a certain picture on there before...except I really don't think I did! It was like a super strong deja-vu feeling about a random picture and it won't go away!
Another example: The other day I had a random memory of someone at my school talking about the plot of a video game. I couldn't think of the video game they were talking about so I looked it up and no video game exists with that plot!
Lastly, I just want you guys to know that the reason I have this specific OCD fear is because three years ago I had a dream that I thought was real when I woke up, later to find it may not be real. That whole experience haunts me still to this day and I've obsessed about it so much that I really don't know whether or not I dreamed it that night or if it actually happened to me a long time ago!

Are these types of false memory experiences only happening to me because I have OCD and I'm worried they will happen, or am I actually losing my mind!

I've been literally sitting on my couch all day just scared that I'm losing it!! Anxiety is at its worst right now, especially since I have off work today so there's nothing else to distract me. Please tell me what you think...is this crazy or all related to severe anxiety?
