Welcome lurker no more.
Congratulations on your newfound freedom. Many of us have been where you are at, so stay in touch, only share what you feel like, and reach out if you need help.
Most importantly, get out and never look back. Depending on what part of the world you are in (I am in South California), there may be a meetup group or some local ex's or soon to be ex's......and many times that can be super helpful. I'm not going to lie, its a little weird at first. Might be worth looking into.
Take care!
