You love to help people. It also seems that you are a critical thinker and can come up with your own ideas(I hope so? You are a grad student). Those who are successful in the tech industry must have the same qualities.
Ok storytime. I know a former grad student who was nervous about the prospects of her PhD program in pharmacology as well. Pharmacy was in slightly better shape then, but not by much. She sat down and thought about what she really likes to do: she just likes solving problems and creating ideas. Entrepreneurs do that when they launch their own startups. She did some reading on startup tech companies and realized that professionals at places like Google and Apple MUST be innovative and look for ways to solve problems. As far as I am concerned, they help people everyday by creating apps to make our lives a little easier. She works at Google now as a software engineer
😉. It was a major and difficult switch indeed, but it seems to have been for the best. She still feels like a scientist to some extent as an engineer and as a Google employee. She eventually wants to start her own company one day.
Am I saying you should be a software engineer? Nah. I am saying to examine the "bare bones" of what is that you really love and its feasibility(relative job prospects).
Good luck

And don't even think about that pharmacy
