I am a newbie but I have been attending a Catholic support group at church. You are totally allowed to take communion and annulity is often given to long term marriages with kids if you wish to remarry in the church or just because that is something you want to pursue.
You might want to see if any of the parishs in your area have a similar ministry. It has helped me focus on the emotional side of things and not mix those decisions with having to take care of the business of things.
Great news about the interview. Sending you prayers and positive thoughts.
