I feel lost

I just wanted to vent here because I really need to get this out. So, I got done with my 12th grade (the results are yet to come) and now I have to give all these entrances to get into universities. The thing is that, I'm not able to focus on anything. I'm not able to study. I also recently started dating and I'm not able to understand that relationship too. I feel so so so overwhelmed all the time and I just don't understand what I'm supposed to do. I can't talk to my parents either because they just don't care. If any of you can offer some advice please go ahead, I could really use some rn.
