Hi Anon2022,
It's a wonderful step forward in self-love that you blocked his number and retained a lawyer! That took a lot of courage.
I've reclaimed much of my self worth by exploring (in therapy and on my own) anxious attachment, the pursuer/withdrawer dynamic, codependence, and covert (or overt!) narcissism. It helped me see the hooks that kept drawing me back in. There are some great podcasts and books out there for all of the above.
This helped me slowly get past self-blame, and self-loathing, and see that I had been in a very unhealthy relationship for a long time. The effects on my mental and physical health were devastating. This took a lot of time (years), and as others have mentioned was not (and still is not) a linear process. But there IS a light at the end of the tunnel.
I'm glad you have a good friend who can be there for you. Depression certainly does suck, and having all of this "mindfuck" on top of it only makes it harder.
As you say, just keep breathing, find a part of yourself to love, and take one step at a time. Though it may seem tempting to just exit as quickly as possible, do take the time to make sure your needs will be provided for. You definitely deserve a secure future.
