Does anyone else confide in unhealthy habits before finding solutions?

CW: Self Harm, Cutting

What my friend said to me felt simultaneously eye opening and made me a feel a bit more vulnerable. "You tend to self harm before you consider that there could be a solution to your problem." The best example I had is when I decided to give up my dream of becoming a veterinarian because I had cut myself so deeply I bled on my chemistry lab, requiring me to rewrite the entirety of my work. At that point was when I decided I will no longer continue studying in the STEM field and change majors.

Does anyone else have a cycle like this? How did you interrupt your cycle?
