Hello OP, I really hope that it will end up being faster and easier than you think it will. You never know though. I just got my divorce in April of last year after we were separated for two years. The worst thing for me was that we separated (I initiated it) during Covid, so we were stuck at home, practically on top of one another. I could not socialize because of the restrictions, so yes, I was loosing my mind. Also, we had a horrible time during Covid as a family, not necessarily Covid related, but like, a lot of stuff, it was brutal. My stress started affecting my physical health, heart palpitations, blood pressure spikes, insomnia. I honestly thought I was going to get sick and die.
I did everything I thought may help that was available to me. I had counselling weekly (it was free for me as a part of my benefits), I meditated daily, did yoga, I even read bible (for the first time in my life). I read a lot and watched a lot of TV, still do, and went for walks every day. I too got sleeping pills and took them every few days so that I get some sleep but do not get addicted to them.
We had fairly straight forward divorce, but I still wanted to get some kind of advice as I did not trust my ex. He did not want to spend a penny and wanted us to apply online, but we literally got stuck on child maintenance right away. I managed to persuade him to at least take mediation, but I had to find someone cheep. We ended up seeing her only once, she was useless and I was intimidated by my ex. In the end I hired a lawyer and we agreed she will help me with most important things otherwise I worked with her assistant which was much cheaper. Ended up paying only few thousand dollars that included separation agreement. Having a lawyer made me feel safer and it was definitely worth it. Hang in there OP. Hugs.
