It's not a magic solution, but considering you work at a FAANG you have sufficient $$$/insurance to pursue therapy/coaching.
Don't misunderstand. Just finding a good therapist/coach is work. You will probably have to "try" a few and they're not cheap. And then once you find a good fit the real work begins.
But, it can be a great investment. Think about it this way. Sounds like you are in your 20s or 30s. You have potentially 30+ years of employment left at $150K+ per year. That is potentially 4 or 5 million dollars, maybe more. So, when considering the costs of coaching/therapy, weigh it against this amount.
Remember that million-dollar athletes and even college and high school athletes have all kinds of coaches to help them perform. Why should YOU not deserve it?
(Side note: why don't companies invest in coaching for their expensive engineers? Considering the high cost of recruiting and retaining engineers, this seems like it would be a great competitive advantage...)
Whether you try coaching, therapy, or some other completely different route I wish you luck. Please know that you are not alone.
