You're so brave for reaching out on this forum; it's a big step and a big one for moving forward - So great work :)
I'm really sorry to hear about your recent breakup; it must be so hard on top of all of this.
As a recent graduate of Year 12, now in TAFE, I suggest sticking with it. But you have to remember that in the end, it's your call to make, not anyone else's, yours only.
I want to ask you a few things, and please don't be overwhelmed with my questions :) (You don't have to answer them, and I'll try to keep them simple.)
Firstly and I'm sure you sick of hearing this one, I know I was getting towards the end of high school, May I ask what sort of career path/s you want to pursue? Don't worry if you don't know, I had no clue and still don't.
What are the positives of high school for you? (Maybe something you enjoy doing, friends, interests, hobbies)
What are the negatives of high school for you? (Stuff you dislike, maybe a subject you dislike)
What is something you want to achieve before the end of 2019? (It's relevant trust me ;), perhaps a goal or reading a book)
My question responses are pretty general right, I know, I'm hopelessly not creative. I can tell you my last year was super stressful, but guess what? I got through it, the same as you will too if you choose also.
I know my post hasn't been the most helpful yet, but I'll await your reply so that I can tailor a response to you.
If you are interested, I have replied to several threads regarding high school during my time there, and it might be helpful to take a look.
These threads have some great insight into your school life, so use them at your leisure.
I look forward to working with you Winkpink; I'm almost sure we can help.
Till next time, C.
Keep your head up and look forward; there's no looking back.
