JSwiss,
I know how you feel, bro. If you have the time, PLEASE read through my introduction and let it soak in. I went through a veritable hell with anxiety and depression. Long, deep sobbing fits in between all-day anxiety that felt like I was in a constant state of fear. It was awful. But slowly it got better. Yes, there were times of "setback" to where I'd think I was recovered, but then suddenly I'd wake up with my heart pumping adrenaline and I'd be back in the shit for days/weeks. Again, IT GOT BETTER. It took quite some time for me to feel human again on a regular basis, but it happened.
Simply don't give up. Find SOME way to keep yourself occupied during the worst of it. Cry when you must. Scream into a pillow when you must. Go out for walks - all day long if need be - but STAY QUIT! I promise you'll get better just like I did. But whatever you do, for the love of God, don't take your anger out on your family. Let them know you're hurting, but don't hurt them. Come rage here. We will take it.
A lot of guys suggest going to the doc and getting drugs. I chose not to do that. Whatever your choice, just stay quit and try with every bit of energy you have to let yourself heal. It takes time but you will get there.
Proud of you for quitting with us, brother.
