Hello:
As a current Holosync user, I agree with what Lord_Shandor has written. I've experienced very similar situations to what you're experiencing. What I have found, that when I take the time to do as he's suggested, and really start exploring why I'm getting upset, angry, etc., most of the problems subside - it's like there's a need for acknowledging what is there, and then just letting go of the negative energy. I use The Sedona Method to help with that. I've also found the Paraliminals to be a great help in assisting the shift in paradigm.
What it all boils down to is, as Bill Harris suggests throughout his material, becoming the Witness - finding a point of detachment from all the crap that's hitting the fan and just observe what is happening, which generally will also provide you with better choices for better outcomes.
Probably a bit repetitious of the other post, but said a little differently.
Couple of other small points: You mentioned just beginning back into Holosync - if you stopped before because of overwhelm or not getting along with the program, perhaps you might want to just slide back in gradually - maybe listen on alternating days. I also found that "time of day" sometimes affects how I respond to the session - perhaps experiment to see what "time" works better for you.
Overall, I hope you won't get discouraged - the fact that you're experiencing what you're experiencing to me sounds like it's doing exactly what it's supposed to be doing - when the overwhelm reaches the point where the brain must reorganize to deal with it, it will move to a higher functioning level. I have a lot of faith in that "model" as Bill explained it in "Thresholds of the Mind" - it appears to be exactly what is happening with me. Get's rough sometime though, so I really do comiserate with you on that score.
Cheers!
