I don’t know what is wrong

I have noticed recently that I am super depressed or feel like I can do anything. This is kind of hard to explain how I feel. I took a mental health test and it said that I am bipolar but I don’t know what this means. I am worried that it is just one more thing that is wrong with me. I don’t know why I am even here my problems are not important sort for bothering anyone who reads this.
