Hello. I will try to keep this as short as possible. I'm 21 years old and lately, I've been suffering from depersonalization/derealization and It's very frustrating. However, the new "symptom" that has me really concerned is that I've been experiencing what I would describe as a constant feeling of deja vu. This is not like the deja vu I've experienced before, this episodes are stronger and last longer, and they scare me so much that I end up having a panic attack right after. Sometimes they are individual and I can have several in the same day and sometimes it feels constant, like a constant feeling of familiarity that won't go away. Everything I do, read, watch on the TV, everything feels like I've done it before. It's been like this for the last 3 weeks. I tried to find information about this and I read that it can be linked to seizures. That scared me so so much, because one day I felt a weird chemical taste in my mouth right before the deja vu. Right now, I am obsessed thinking I'm having seizures or a brain tumor causing said seizures, That scares me so much, I can't think of anything else. Has anyone felt something similar? Can anxiety caused this weird Deja vu episodes? Please help me, I'm so worried, I fear that I'm going crazy or that I'm going to feel like this forever. Thanks in advance, I will appreciate any reply.
I am sure this must be very scary for you but I wanted you to know that déjà vu is extremely common with anxiety. I have had anxiety for over 30 years and I have had countless déjà vu’s. It’s actually a part of that D personalization or D realization. depersonalization is your brain’s way of blocking out the stress and anxiety. That’s why it feels so weird. it’s trying to protect you from stress. None of which is harmful but I know how weird it feels.
there are countless people who get that mentallic taste in their mouth but that can also be from anxiety also. I’ve had it many times . all of these anxiety symptoms plus hundreds more are not harmful but they are trying to tell us that we have too much stress and anxiety. The symptoms are just away your body communicates with you
. The best thing you can do for yourself is completely relax your mind as much as possible. Get some counseling for anxiety because it’s very helpful and they can give you ideas on what to do. Basically learning anxiety management is very important. don’t take life too seriously because it can wreak havoc on your health and it’s really not worth it. Take time out for yourself during the day to do some slow mindfulness deep breathing to calm your mind. Get some exercise and eat healthy. it’s a process but if you take one day at a time you can feel a lot better soon.
of course everyone should have a check up with their doctor at least once a year. And more often if needed. But anxiety is the number one reason that people visit counselors so there are millions of other people just like us who are dealing with this.
never ever stop caring for yourself! Sometimes we just have to put ourselves first before we can help anybody else. I hope this helps! You’re going to be fine and don’t freak out about the symptoms because they can make them worse. Breathe! 
Thanks for your reply, I really appreciate it. It always makes me feel better when I learn that others are going or have gone through the same.
Since I wrote the post, I’ve had good and bad days. I had two days without a single Deja vu which is the longest, since this all started. Today, however is one of the bad days, I’m trying to not feel so down. I’m also trying to follow your advice and try to reduce the level of stress in my life but I’m finding it really hard with school and the pandemic and everything going on.
This is so incredibly hard, there are days where I genuinely believe I’m going to have a psychotic breakout, the derealization is really making me feel like that.
I’m just hanging in there, hoping that I can get professional help soon and hopefully go back to how I used to be.
Thank you again for your kind
words. I hope you’re doing great
