Yes, and it's a reason it's reassuring to be here in the forum too. Seeing all this described as 'normal' is just a big, huge relief, I know. Seeing others posting about feelings and behaviors which are really similar tends to be awfully validating also, for whatever reason, at least for me personally.
I hope you can find relief and information here as well, while waiting to get into therapy. There always seems to be an article which answers some question one has been thinking of, or re-reading one you understand something better than you had earlier.
Best wishes, as you continue with your helpful book, and here. Take care,
Anni
