I just got back from visiting a friend in Vietnam... He recently used online therapy to navigate the lack of local options. Maybe look into betterhelp or other apps and outlets to find something suitable as i think it will really help you. So sorry to hear about your sitch mate.. i lived in Asia for years and understand the local police rarely wanting to help expats/foreigners.
keep that chin up / surround yourself with friends and good people / stay busy and work at things slowly would be my advice.. be patient and kind to yourself! And you always have an ear or friendly chat available on here.
Good luck
