The odds of having an identical situation from the one you had previously are very low. Based on reading your posts, are you a long time anxiety sufferer? My best advice to you is to talk to a doctor about anxiety. It's treatable and it seems to interfere with your life a good deal so well worth the effort to overcome it.
With regards to a condom breaking, if this is indeed a second time this happened to you, the advice is identical to the last time you asked about it. The odds are very low at less than 2 percent from a single unprotected sex episode. You will need to test at 28 days with a DUO test but would not be overly worried.
When did this happen? Long time ago? I'm asking because I believe you asked about this already based on your previous questions.
