First of all, I'm so sorry you're struggling with this during what is supposed to be the best time of your life (college). I'm new to nursing school and have not started clinical yet so I have no specific advice there. But I did have a similar experience that I will share...
I went through the awkward college years when I was pursuing my first degree. I always preferred studying alone with a book... no crowds, no groups, no speaking in front of a group, and definitely no doing things with others watching (and in my mind... judging my every move).
It wasn't until years later that I was able to overcome this by having more confidence in myself. Don't be afraid of making mistakes. It just gives you more material to learn from.
Try to figure out if you've lost your passion for nursing because you're having difficulties - or if you're having difficulties because you've lost your passion.
Have you considered talking to a counselor? I think they could really help navigate you through all of these feelings.
In the meantime, don't be so hard on yourself and I personally would like to see you post at least two things that you do WELL.
