Hey, don't apologize for venting! My whole post is basically a vent. Right now I'm working part-time in a research lab, it's not nursing pay of course but I'm not miserable and feel like I can actually enjoy life again. Also taking Physics and Calculus I this summer semester
My advice to you is to take some time off work, if possible, and take care of yourself. You sound very burned out, just like I was. During that time, think about what you might enjoy doing...maybe it's something else in nursing that's more "introvert-friendly" like clinical research, or something else entirely. Then shadow some professionals in that field...that's one thing I wished I did before jumping into nursing (I was young and naive). Life is too short to be miserable, is what I've learned.
I was afraid that I would be disappointing my family by leaving nursing, but it turns out that they were worried about me because I had lost weight and wasn't taking care of myself. Most people understand that nursing is a tough career, but don't understand the extent. I would explain to your family what you've been struggling with. Remember that you are not a failure for finding out that nursing isn't for you...many, many people go into a career and find out that it's not for them. That's where the second-degree students often come from (and many go into nursing!). I'm sorry I don't have more advice, but just remember that your physical and mental health are very important and if you are sacrificing your well-being to be a nurse, then it is not worth it. Best wishes :)
