Whenever I feel like this, it always has a way of encompassing my whole vision. I've found that eventually I always realize the same thing. Who's to say what right even is? Just because it didn't go how you were hoping does not mean that you were wrong. Different does not equal wrong. I just had to learn what "wrong" really meant to me.
Last time I felt this way was around a year ago. I had just accomplished a lot of goals, and the potential of what to do next seemed limitless. I wanted to do so many things, so many that I over extended myself and actually tried to do a million things, but just about all of them crashed down on me. "I can't do anything right" was a common thought then. But it left me when I realized I wasn't "Wrong" to try any of it. I just tried to take on more than I could handle.
