Yes, I was anxious with him and attributed it to other things (because I didn't WANT to attribute it to my choice of being with him). 3 months after our break up, I am still experiencing anxiety to the point to where I have been avoiding social situations (something as simple as going to the grocery gets me all spun up). My doctor had to double my anxiety meds just so I could get out of bed and go to work. I am working on myself, working on taking responsiblity for my choices and working on forgiving myself (which is by FAR the hardest thing for me), the anxiety will ease as long as I continue to discover who I really am and set boundries. I've had blinders on for most of my relationships; I have made excuses for others' behavior and have been far to harsh on myself. I believe that working on myself every day will eventually bring peace.
Hoping you find your center; may peace be with you.
