I think it took me about 6 months to feel like I was on solid ground. I think some of it can even be chemical. You might want to read a little bit about PAWS (I grabbed an article from the internet - see below):
Why We Don’t Get Better Immediately: Post-acute Withdrawal Syndrome (PAWS) | What...Me Sober?
I had some problems with depression predating my drinking, so I knew that would also come into play when I got sober. I think it helps to see our issues/feelings as separate from our drinking and get the extra help we need.
I hope you feel better soon. :ghug3 Thanks for posting about this.....I think we all go through these things. Just remember that alcohol isn't a solution. (Are you doing anything for your recovery on a regular basis?)
