Weak-Concept-4376's journey

I recently found myself in a tough situation at my job at an animal hospital, where I've been working for a couple of years. The environment has become increasingly toxic, with understaffing issues and a heavy workload that I wasn't compensated for. Despite my dedication, I was denied a fair raise and told I wouldn't see one for another 1.5 to 2 years due to profitability concerns. I've endured mistreatment and bullying, which culminated in a panic attack that forced me to leave work unexpectedly. Although I was apologized to and asked to stay, the situation has not improved, and I've reached my breaking point. I had a vacation approved for a little over a month from now, which I requested well in advance. However, I now feel that I need to resign before my vacation, as I make more money working from home and want to focus on that full-time. My coworkers have expressed that they really don't want to lose me, and I've been receiving unexpected bonuses, which makes me feel guilty about leaving. My therapist agrees that it's best for my mental health to move on. I'm worried about burning bridges by resigning before my vacation. My family suggests I wait until after my time off, fearing that my vacation pay might be withheld due to the disorganization at the hospital. I want to ensure I can use this job as a reference in the future, as I've worked hard during my time there. I'm looking for advice on whether resigning now would damage my professional relationships.
