Try not to label everything within you as good or bad. Or if you have to always try to find both in every situation. You will see that accepting your fears (outcomes you label as just bad) will help you accept yourself. If you're holding regrets then try to ask yourself the question whether you did your best with the amount of knowledge you had at time. If you can answer it with yes and it was still a shitty outcome then that means you had to learn something new to realize that. You have regrets because you've learned the lesson now. You might be able to see the value in that at some point and see the good in the bad experience.

But all of this works if you truly believe your own word. And you gotta practice to be honest and start trusting yourself before you can truly believe the "yes" or "no" to your own questions.

Good luck there mate, in the end you will have to create your own tools how to best deal with yourself and noone else's methods will guarantee you that. Only you can know what's best for you, and finding what that is is hard enough in the present. Impossible to decide for the future so it requires some giving in as well.

In the end we're all going through the same journey looking from a further vantage point and if some people can do it, so can you! <3
