Hello and welcome to our SR community.
Truth is, you could continue to avoid all that stuff. However, you are seeing the consequencing of doing that and now you are becoming willing to do something different. You feel how far denial & refusal got you and now you are getting honest about it. You are experiencing the results of having a closed mind about a variety of issues, but seem to have a desire to something about it. i've made a tremendous amount of progress in my recovery relying on those three principles; Honesty, Open-mindedness, & Willingness. You can too if you are ready to take certain steps!
Why not go to an N.A. meeting today and begin getting to know everyone?
