Hi Slothy......I am glad that you posted here. I am also glad that you got out sooner, rather than later!
Yes, alanon would be very supportive for you, right now. The people there wil be understanding and not judgemental.
I suggest that you begin reading "Co-dependent N o More". It is practically classic reading, around here.
Also, peruse the "stickies"---the articles at the top of this main page.
The reason that I say this is because we often carry our same baggage (we all have baggage) into future relationships. We humans tend to behave in patterns. Getting to know and understand yourself and what makes you "tick" is the inoculation against making the same mistakes, again, down the line.
Yes, you are going through the natural grieving process....which will end in due time.
I urge you to take advantage of this pivotal time in your l ife to gain all the self-awareness and knowledge that you can get under your belt. It could change your whole future.....for the better......
