I'm afraid I'm not going to answer many of your questions but I am going to say some stuff still: It may be stressful but try to embrace the change and remain positive. Take it as an opportunity to reevaluate other things in life if possible e.g. how much physical stuff you need in your life and if that stuff makes you happy. Change and hardship/being uncomfortable is good for you in moderation and trains you to weather bigger storms you may encounter later in life. The bay area is a fantastic place to live, especially for a young person in tech, so try to remain positive although I can understand where you are coming from, and your stress is totally reasonable. The climate out here (both physical environment and cultural) is fantastic, be sure to seek it out. Good luck and congrats on the change!
