I have learned many different thing thoughtout my life and some the best advice that I can give you is not to over think any situation. Overthinking a situation makes it way harder then it needs to be. If you take a second to breathe and calm down it will make your life easier. You know the answer but can't find it if you try to find every possible reason to think that your first guess maybe wrong. Just take a chance and calm down. Then you will see how easy you can solve a problem.
