I'm too tired at the moment to think about finances... I'll come back to that at a later time.
Realizing that you spent this semester learning from home certainly puts you at a disadvantage. I was certainly distracted this semester as well and didn't feel I had the same type of support available (I did, but it wasn't like being able to walk into an office, throw my bag on the floor and cry and feel better when I left). Before you give up on nursing (unless that is really what you want to do - it does happen for some people) - look into a few things.
1) see if there is any grace for failing during a semester when you weren't allowed to be on campus. Maybe they will hold your scholarships under the circumstances - the worst they can say is no.
2) Don't worry about paying back your student loans right now - if the grace period ends (mine are 9 months but they were 6 the first time I graduated) then just call for a forbearance - they almost always grant them while you are still in school. It does start over after you complete school, so it isn't "wasted" on that time in the middle. You get a do-over.
3)delve a little deeper into how you are understanding adult health. How are you studying and how are you learning? Your pre-reqs were all about memorization - but adult health isn't. I am assuming that Adult Health is similar in nature to Med Surg - which is how everything in the body works and works together. It isn't enough to know that one can suffer from right sided or left sided heart failure - but you have to understand what happens during right sided heart failure (everything backs up, peripheral edema, etc). and that it can lead to left sided heart failure - where you start getting crackles and blah blah blah. You need to know what medications will be used to treat this and what their intended effects should have and what the adverse effects are. I did a lot of questions to learn, but that's how I learn. I did over 3000 questions in Prep U for Med Surg and over time all the pieces started coming together for me. I can't say that I would have done well in Med Surg I if it was all online. I would have certainly done better in Med Surg 2 if I would have been on campus.
4) What are you passionate about? My daughter wanted to be a vet when she was younger. I always joked with her that she was going to have to put her hand up a horses butt... know what? She did it. She's not a vet. She realized that she hated grinding their teeth because there was a balance between keeping a horse on their feet and enough pain meds to make them comfortable. Luckily she had the opportunity to work on a farm while she was in middle and high school and even was able to be present when they had to put down one of her favorite horses. She put a tube down a horses throat and delivered a foal that didn't survive. All the bad and grinding some teeth made her change her mind.
I know its a little rough right now. Whatever you are passionate about - try to go do it. I realize life is on hold or closed at the moment - but If you can - try. I'm also not kidding about the welding thing - you don't always need a 4+ year degree to make money. Maybe not welding specifically - but don't rule out things that don't require 4 year degrees. Also - I'm here to tell you that while money makes life much easier, it doesn't necessarily make you happier. Happiness comes from within. Money makes things tolerable. Student loans also get paid off. Mine were paid off precisely 2 years before I started them over again...
Tech jobs.... many don't require a CNA. Once you pass Fundamentals in Nursing school - that usually gets you in the door. Not sure if you will make more $$ or not, but it can be an option. It will also help you determine if you really like being in nurse type situations (you do different stuff, but you see first hand what goes on).
So talk to me about your passions - and why didn't you go that way to start with?
