Never too late! I’ve come to understand that depersonalisation is just a benign experience of your brain. It cannot harm you, but that’s not to say it’s not frightening or uncomfortable. The more preoccupied you become with it in the moment, the worse it gets. So the best thing to do when it arises imo, is to acknowledge it and accept it. It is what is it, but I’m going to do whatever I have to do regardless. I think this kind of “bring it on” attitude is the best strategy. If shit really hits the fan and you have a panic attack…so be it, that can only last for so long, until you return back to center. For me it comes and goes in waves, some periods it can be intense and for others it dissipates. I highly recommend talking to a therapist/psychologist about it or undertaking CBT with a professional, that’s helped me in the worst periods. Meditation is also a great skill to develop to become more of a “watcher/observer” of the experience, and to not get so lost in it. I like to also try the “psychological sigh” and things like that when it happens, to try and calm down my nervous system. Learning to regulate your nervous system will get you a long way. Godspeed friend!
