Hi hollow! Welcome
I understand exactly what you are experiencing and will be going through it hard myself starting tomorrow. It is great that you are starting a journal, there is something very relieving about getting your thoughts on paper. I have also experienced panic attacks, honestly the only thing I can think of right now is learning a breathing exercise for when you have one, after all that breath seems to be the most lost thing in a panic state.
Also, you are going to be foggy, mentally, for a good amount of time, maybe up to a month depending on usage. but i promise it clears! best of luck to you!
