Changing my degree from social work to accounting. Need some advice

Hello,
I am soon to be 22 year old student in her 2nd year of social work. I chose this field because I enjoy sociology and psychology and I find that social work blends these two subjects well. I also have been interested in helping people. I have done really well in the classes I had to take and had a pretty strong GPA until I had to do the practical fieldwork course. I failed it once and I was in the process of retaking it over the summer and will most likely fail it again. I am getting feedback from my supervisor that I might not be suited for this type of work since I am not the most outgoing and social person and I struggle to connect quickly with strangers. I am more introverted. I didn’t realize at the time that it would have a huge impact on me being successful in the career and the fact that I had to interact with so many unknown faces on a regular. I taught it would be more like one on one counselling, but I was wrong. Brought down my gpa to 3.4

I now have to accept the reality that maybe it is not the right career for me and I am feeling lost. I feel like I am a failure and that I made a huge mistake choosing this field. I wasted 2 whole years when I could have been studying something else. Now I have to start over.

I taught of accounting because I have always loved problem solving and math and I am perfectionist and very detail oriented. Has anyone had similar experiences making a switch in career paths from two very different fields ?

How would you go about making a big decision after failing out of a program ?

Any advice would be appreciated.

Thank you in advance
