Lost and Found

Hello All! Ok so here it goes... I was wondering if anybody could give me some insight into nursing versus respiratory therapy. I'm currently in my first semester of nursing school, and I am really mentally struggling with it. I was looking at different options in case nursing school doesn't work out and something I saw was respiratory therapy. I've been doing research and one of the main things I found was that it can be kind of a "dead end" career. What I mean is that with nursing, there's more job opportunities. Is this true? The info I saw was from a few years back and I haven't seen anything posted on here recently so I just wanted some feedback. I would just rather switch programs now before I get in too deep you know? Also, program difficulty wise, which is more difficult? I know nurses, make significantly more money then RT's but this isn't simply about money. I want to help people, and I know both professions do that. Any information/feedback would be greatly appreciated! :)
