Procrastinating so bad, Help!

I'm feeling overwhelmed and stuck. For the past four days, I haven't opened my laptop (I wfh) or applied for leave from work, and I'm scared and worried about the consequences. To understand why I'm struggling, I need to share some background about my year. 2024 was incredibly tough for me. My seven-year relationship came to an end, and I was diagnosed with depression and borderline personality disorder (BPD). I started taking psych meds and attending therapy sessions, which helped. However, my parents were concerned, so I gradually reduced my medication until I stopped taking it entirely in January. Since my breakup, I've struggled to find motivation or interest in anything. There have been times when I felt so low that I considered harming myself. I've been wasting time on social media, mindlessly scrolling through Instagram, and swiping through dating apps in a desperate attempt to fill the void. But it's only made me feel more lonely and empty. The past week has been particularly rough, and I've been avoiding work despite having a lot of pending tasks that are already past deadline. I know I need to snap out of this funk and get back to work, but I just can't seem to muster the energy or motivation. My medical history is complex, and I've faced significant health challenges in the past. I battled cancer twice as a teenager, underwent two major surgeries, and completed 12 cycles of chemotherapy. Despite all this, I'm still trying to come to terms with the end of my relationship. I feel lonely and desperate for connection, which sometimes leads me to seek comfort in unhealthy ways. One example of this is when I got a tattoo of my ex's name after we broke up, hoping it would show her how much she meant to me. I know it sounds impulsive, but I was in a vulnerable state at the time. Right now, I'm seeking help to overcome my procrastination and get back to work. I have a lot of tasks to complete, and I need to find a way to stay focused and motivated. Any suggestions or advice would be greatly appreciated.
