Did you struggle with jobs you hated?

I am in the military and I hate it! Enlisted. 😒 I feel like I downgraded and settled for less. I went into deep depression and was very angry and bitter about my stupid impulsive decision. These are just not my type of people, culture, or lifestyle. I don't want to go into intricate detail because I know I will offend many people. I just got accepted to the Doctor of Physical Therapy program and I am excited!!!! I remember shadowing in college and loving it! I have 4months left in the military. I start the program in fall. I am in such a better mood that I finally got off antidepressants. I am happy! Anyone get fired or struggled with work until you found the career you loved???
