Your credentials look great!
On a general note, I work with graduate students and their best piece of advice for applying to grad school and receiving acceptances and rejections is that it's best to recognize that graduate schools accept students on different merits. For example, if you apply to graduate schools that are thesis or research based, potential supervisors play a role in the types of students they want to take on because they have to carefully consider a) if they'll have funding to do research and b, which students they would want on their research. That means it can vary year to year how many students they take on.
For other programs the requirements do play a role. For example, if a school wants their future applicants to have a strong mathematical background, that plays a huge role. If a school want students with diverse experiences, that affects their who they select to be a part of their cohort. I've seen students rejected out of medical school who have perfect GPAs and great volunteer experience simple because they scored a decimal point less than the person that was given a seat.
The healthiest way to cope with graduate school admissions and not get stuck in an unhealthy mental loophole is to recognize that they accept on different merits and after your application submission it is out of your control. You submitted the best application that you could and it's best to occupy this time with hobbies, work, or other activities. Don't let the decisions of graduate schools reflect on yourself because there are many variables out of our control
