You are incredibly mature for a 19-year-old! Thank you so much for your kind words. Sometimes it is easier to give advice than to receive it. Ironically, I have worked in Higher Education for over 15 years. I wish I knew and was diagnosed with ADD much earlier, as I think I would have done better in school.
Having said that, I can safely say that it is OK to not know what you want to do for a career at this stage of your life. Most people change careers three times and the average number of jobs is eight! I recommend checking it these assessments as you may find them helpful. you can take your pick from the many on these two websites. Lots to play around with and maybe some that will lead you in the right direction: you can take your pick from the many on these two websites.

Also, if you have not already done so, I recommend reading the book What Color Is Your Parachute? 2018: A Practical Manual for Job-Hunters and Career-Changers. https://www.amazon.com/What-Color-Your-Parachute-2018/dp/039957963X
Connect with as many resources on campus as you can. As my brother tells me, you just have to work out work everyone else! See, I need to listen to my own advice LOL.
