OK so you feel mentally like **** - but that will change
Feeling shame is optional, some do and some don't (I didn't)
It is a constant fight at first - but that will change
Loneliness sucks - but that will change
How long did you drink daddoo? I bet it was longer than 6 weeks. Things don't magically get wonderful after 6 weeks of sobriety. Staying sober is hard work. Are you using any kind of recovery program to stay sober? If not I suggest finding one that best fits you and start using it. At six weeks you gotten past the physical part. Now it's time to work on the problems in your life. That's where you need a plan on how to do that.
