I decided to work on my chakras to get rid of my dissociation but it made it way worse
This is a guess: There is a powerful reason why you need to dissociate. We learn to dissociate when what is happening in the present moment is too much to feel. Dissociation is a tool the brain uses for our survival. With PTSD, we haven't learned that the danger has passed and the brain still thinks it needs to protect us. Dissociation is one of its tools.
My guess is your brain is doing its best to keep you from feeling. Working on your chakras may have started to open you up more to intense emotions and memories, which felt like a danger signal to your brain. So it redoubled its efforts to keep you safe the best way it knew how: by dissociating so you couldn't connect to the present moment, because to your brain, present = danger.
This tells me your therapist is bang on about the coping skills. I'm guessing you may be frustrated because it feels like they aren't working fast enough, and you wanted to hurry things along? Sigh. These therapists, making us take our time. Sometimes they actually know what they're talking about. :)
Is this a trauma therapist you are working with? Is the intent to work on trauma release once you have learned more coping skills?
I may be off base with this, so take what works for you and leave the rest.
Edited to add: I may be making things confusing by saying that to your brain, present = danger... while also suggesting grounding, which is basically coming back to the present. What I mean to say is that working on your chakras may have flooded you so the present doesn't
feel safe, even if it is. I suggest coming back to what feels familiar to ground yourself. Try connecting to something outside of yourself, it sounds like the energy "inside" may be too much right now. Hopefully I haven't muddled things still more, I feel kind of like I'm talking in circles.
