Suggest Treatment For Perforation In My Appendix

Hi, my appendix perforated/ruptured on Jan. 10/14 and I was put on a course of antibiotics in hospital for 1 week, (pipercillon), after discharge I was given amoxicillan/claviculon for 10 days, and found that was not working so family doctor changed me to cipr/micro-flagil (10days) and that seemed to do the trick. An U/S on Feb. 3/14 shows 9mm left of my appendix and I am wondering if I still need surgery to remove that piece. I have not got my energy back, but every day is a little better, but I am so tired after 8pm at night I cannot keep my eyes open. I was supposed to see the surgeon Friday, Feb. 14th but he cancelled due to an emergency. I have had to take a considerable time off of work and lost another day Friday, so I am trying to decide if maybe I should just forego the surgery, however this tiredness makes me wonder if I am still recovering from the appendicitis or does this indicate that I should have it removed, or is this common to still be so tired. Prior to this happening, I never went to bed until 12-1 in the am and 5 hours sleep was plenty for me. I work as a lab tech in a busy Family Health Team for the last 7 years, full time on the go, so this is very out of the norm for me. Any thoughts? I would appreciate your opinion even though my doctors at work keep assuring me that is normal, I am still recovering, etc., no one has actually said if I still need surgery. I really don't want to take more time off work to see the surgeon and maybe have him cancel again. thank you for any advice you can offer.
