So here's the story, I'm studying Bio, Chem and Geography at college. I'm doing two extra 1 year subjects but one will be finished in like 4 days. Truth is, since I've started college I've been struggling and I have a massive fear of faliure. I want to be successful and I've been putting work in- just not seeing results as drastically as I'd like. I'm still a first year so it's ok but I want to be amazing not mediocre... That aside, assume I've done great in all of my exams.

I've been very passionate about travelling since I was about 13, and I went solo travelling when I was 16 for 8 weeks! It was seriously one of the most amazing times of my life. This was right after I'd finished high school so I had no work to worry about or anything of that matter. BACK TO MAIN QUESTION: I want to study in an Australian University as a foreign student, and I've considered Melbourne as a top choice in an ideal world. (Please don't put me down I'm trying my best). I'd love going to America too, but it's pretty dystopian there right now- besides, who could resist that charming Aussie climate eh? And I can't really speak Japanese so that would be insane. My plate is too full.

What would the first application steps be? Are there any specific requirements? How can I apply for a visa? Does it all depend on grades? Would you advise taking an apprenticeship there instead? Are the universities really expensive? I've lived in the UK my whole life but I'm not actually from here by blood, I'm half Polish half Bulgarian. Would this have an effect on anything??

God I am 17 years old and already deep into the rat race. Where did I go wrong?

Extra story I also don't even know if I want to study Biochemistry anymore, and that tells me all I need to know- once passion starts waning it is really hard to get back to where you started. It's definitely because I'm facing hardships, I know that. Before I wanted to become a biochemist, I was really into the idea of becoming an architecht. Should I just retake year one and change the subjects that have been making me feel so miserable and useless? Also to any Australian students, is Biochem/architecture harder? Is there a massive range between the net earnings? Is there any life advice you think I'd find useful right now? I think I should rename this and call it r/17yearoldratrace ...

Back in highschool I was genuinely a picture perfect model student for the 4.9/5 years I studied there, however in the last months some personal things happened at home and I really sturggled to get revision done, as well as actually be ME. My mental state had been completely throttled and I lost my spark. In the end my exam results were like, super dissapointing. Since then I've felt insecure and like I'm secretly a stupid person behind this all. It was pretty traumatic.

Well, I won't type anymore since I doubt this will ever be seen and I've got work to do. Thanks dearly to whoever responds!
