For me, once our last court date was over and all the legal BS was done (or so I thought, lol!) I felt like the weight of the world was lifted from me. Of course I was still sad but so much anxiety just vanished.
After that final court date my sister took me to lunch. I know this because she told me so. Ask me where we went? No idea. What I do know is once I came home from court/lunch I fell asleep on the couch and slept for 16 hours. My phone had tons of missed calls and texts and I never once heard a thing. My mom was ready to have the police break down my door. I think it was the best sleep I ever had in my life.
I think once you have your things and the legalities are more settled some of your anxiety will diminish. I was stressed to the max and until that final document was signed and I felt the relief, I don't think I realized (fully) the level of anxiety I felt.
