How do you tell burnout/misalignment from avoidance when you have ADHD and grief?

I’m a qualified mental health nurse with ADHD, currently doing an MSc that’s started to feel misaligned and actively harmful to my wellbeing. I recently lost my teenage cousin, and while grief has intensified everything, I was already struggling to engage with the MSc beforehand. I’ve been granted an extension, which brought relief — but also made me realise I don’t actually want to do the work at all. What’s confusing me is that during my nursing degree I did push through overwhelm (even after losing my granda), finished, and did well. Because of that, I’m scared that stepping away now means I’m reverting to an old “ADHD dropout” pattern rather than making a wise decision. The difference this time is: • I already have a career I enjoy • The MSc isn’t required for my future plans • Engaging with it worsens my mental health • Imagining life without it (working, saving, planning my wedding, possibly moving abroad) brings noticeable relief I’m trying to work out: • how to distinguish burnout/misalignment from avoidance • whether it’s reasonable to step away even if I could technically push through • how to trust my judgement when grief is also present I’d really value honest perspectives from people who’ve paused or left postgrad study after already proving they could finish hard things. TL;DR: Qualified nurse with ADHD, grieving, doing an MSc that feels misaligned and harmful. I can push through, but it comes at a big cost. Struggling to trust myself because I’ve pushed through before. Looking for honest advice from people who’ve been there.
