Hi Lauren57r,
You've already been given some great advice. I just wanted to add that your story is very similar to my own experiences. After high school I went straight into a uni degree and it actually wasn't until several years later that I realised I had made the choice, not because it was something I was particularly passionate about, but because I had felt pressure to make a decision about the future and went with a degree that i felt most aligned with my passions. If I could go back and do it over, I would not have gone to uni straight away. I always had the belief that you HAD to go to uni to be 'successful' or get a well paying job and that simply isn't the case. In the end all i gained from that experience was student debt and a ton of stress for something that wasn't worth it. I'm not saying you shouldn't finish your course or swap into a new one - my point is that if you are not 100% sure about a course then why not focus on work for a while and built up savings for things like a house/travel/etc. You can always go back to uni later on when you are sure what it is you want to do. For me, I worked for awhile and then one day woke up and felt like a light switch had turned on and I knew what it was I wanted to do.
In the end, maybe you will find this helpful or maybe you won't. I just wish someone would have told me that I didn't have to go to uni, that not going wouldn't make me a failure or somehow less intelligent/successful than my friends who went. Maybe if they had, I wouldn't have as large a student debt as I do now and perhaps I would've followed my heart and travelled first.
Uni is always going to be stressful, especially when you are living away from home and don't have that support system around you. My advice is if you're going to study, find a course you actually love - believe me it makes a hell of a difference when you are up late working on those assignments or stressed out over the workload. If you do decide that teaching is something you are passionate about, I would finish the degree you are on now as with a completed degree, you would be able to do a masters of teaching (which from memory i think only takes 1 year) as opposed to a 3-4 year bachelor of education.
P.S. Please don't be embarrassed over failed units, it happens to everyone and at the end of the day if it takes you 3 years or 10 years to finish your degree, it will still be worth the same and employers won't see that it took you longer.
