Humble, I was just in your shoes a little over 2 weeks ago. Its easy for me to write this, but it was very difficult for me to do. Let go of the shame and hurt. I was a wreck for 7-8 days. It only got better once I let it go. I wont forget what I did, but I stopped beating myself up over it. The sooner the better. It is normal to feel the way you do. But talk to someone, get to a meeting and talk about it. It helps, or at least it helped me. Stay on the site read, read and read. Ask questions if you need to.
