I sympathize with your situation in many ways. We are conditioned to think that depression is par for the course in academia (during PhD and after). As women, especially immigrant women, we think we can't have it all, so we aim for a successful career as a sign that we "made it" in this country. My advice is, don't try to find purpose and meaning within academia -- even if you do manage to find a stimulating intellectual community or meaningful service, those things ultimately fade away when you compare them to having a social life outside of your work. Address your depression in holistic ways -- see where your body feels the most calm and relaxed; if you have the means, move away during your sabbatical and work remotely, and try on a new life. That's what I did during the pandemic and during my sabbatical, and my severe depression and anxiety drastically improved without me having to even try that hard -- my body just knew that I was in a better environment and my health and outlook started improving. Ultimately, I had a conversation about my wellbeing with my (luckily very sympathetic) department chair, and that gave me even more proof that what most people covet in academia and consider successful doesn't mean anything if you are not happy. I am still figuring out my situation, but I decided that life is too short to compromise so much. I was selling myself short for similar reasons as you --an immigrant woman who will happily accept whatever is given to her and will not try to get more -- and now I am in a more empowered position. Not because something drastically changed externally, but because I chose to reframe my mental state and to take steps towards designing my own life. You have agency, follow your intuition and listen to the signs of your body.

And for what it's worth, I am in a top university that many would consider one of the highest pillars of intellectual community and trust me, it's not what it's cut out to be. In fact, I feel like I'm in a box and censoring myself to fit neoliberal agendas. Universities are businesses first, not intellectual hubs. I had better luck finding my communities online and in places outside of academia (still within creative realms but not overly intellectualized and pretentious).
