Regarding your reality doesn’t seem real feeling, research “depersonalization”. I have an anxiety disorder and this is what happens to me in stressful situations. A good portion of my anxiety stems from being obsessed with my husbands addiction. The past week I have felt as though I’m dreaming. I catch myself thinking “is this even real” all the time. I also share the feeling about “am I overreacting”. I think these feelings come from so many years of manipulation from my addict. I let his problem become my problem. This is what I’m trying to focus on NOT doing right now.
