I've been quite lucky in my exit process. It's hard for me to give advice when my situation will probably not be as hard as yours, brainwashed-from-birth. But I can at least tell you that reaching out and connecting socially has helped tremendously. I'm meeting cool people at every social event--much better than the "wasteland of evil people" the WT tried to spook me with!
You may not have what I do, but just look for the good people in your locale. It's a start. Keeping busy with all the things you couldn't do will help, at least for the time being, to distract you from Borg issues.
This board will certainly help. But even I found it good to take a vacation from reading about Borg drama, just to keep my sanity.
If you dwell on your hatred, the Borg wins. If you give them the middle finger, you win. You've gotta be flippant about it.
