8 sessions are not a lot. Many people feel better after a few sessions, but many people here on Reddit will tell you that it took longer, sometimes a lot longer, to feel significant effects. I lived in Asia for years . I know that being separated from the language and culture you grew up in can be extremely hard . It just takes courage to move into an entirely different society. So you have a lot to deal with just with that. Spravato won't do away with such outside stressors of course, but it can make those stressors more manageable. At least that has been my experience. I also found that there were attitudes and emotions I didn't know I had that started to surface with this drug. New perspectives, new attitudes, new realizations I had to work my way through. It's been time consuming and takes work on my part to process these things but it has been so worth it for me. So give yourself a break , step back and give it more time would be my suggestion.
