I'm in Year 13 and really struggling with A Levels (I've gotten two Es in my mocks and one B). I used to be a good student in GCSEs (got all 7s and 8s despite having studied in the UK for only four years) but I just can't get myself to study in Sixth Form. I know very well how important it is, and I've done plenty of research to make sure I don't lose motivation (spent hours making countless revision plans, removed any visible distractions, did not partake in any 'pleasant' activities for almost a month before my mock (like watching a tv show or playing video games to make sure i don't get too carried away and get distracted...) yet I ALWAYS seem to lose motivation. It's like I can't even control it.
Also, I'm likely to be neurodiverse (ASD and inattentive ADHD) and I've already made a referral with my school but waiting times are terrible so nothing's probably gonna happen there. But I'm REALLY unmotivated and I feel like it's all outside of my control. If I put in the necessary effort and worked hard, I'd be able to succeed just fine. But I just can't do it. I can't focus in class even if the teaching is well structured and there are no obvious distractions. As a result LOTS of time gets wasted there, I basically get nothing done. I'm more productive when I'm on my own but I've barely got time to do that because of homework and material to catch up on and I have incredibly low energy levels, especially after a school day. I have a really short attention span, I'm typically late and really forgetful and my organisation skills suck.
I'm really worried and frustrated right now because I don't want to be seen as somene who's 'just lazy' and doesn't take things seriously. Sorry if this was messy and all over the place but it anyone has any advice please let me know.
