It's inspiring to hear how you are changing for the better because of Eckhart's teachings. I'm sorry you have to go through such a tough time in order to find the peace of Presence.
My experience has been similar to yours (8 months practicing Tolle) in that I had trouble with depression, anger, fear, etc., except that mine manifested mostly at work. As I've progressed in Presence, those emotions are very much in the background now, and I am at peace and rejoicing in life. I didn't have to do anything special other than practicing Presence and daily meditation. I just keep Presence in the forefront of my mind all day, as best I can. I hope it will be as easy for you.
Two other teachers I have found helpful are Byron Katie and Candice O'Denver. You'll find both in an online search. Katie teaches how to analyze emotions that constantly intrude on Presence and let them go. Candice amplifies Eckhart's teaching about Presence by saying we need to practice many small moments of peace many times a day, and that by doing this, we learn to predominantly live in peaceful Presence.
Hope these other resources and Eckhart help you and that you get through this difficult time OK. My heart goes out to you in your struggles.
