my mother went through my instagram messages and freaked out on me for talking to boys, lying to her and staying up

for reference, i'm 18 and i live in a shit third world country. i had my instagram logged into her phone last night and while i was up at 2am texting some dude and she suddenly barged into my locked door using the keys (common habit) and started yelling at me for 'breaking her trust' and 'staying up talking to boys' and began accusing me of lying to her (which is true). she took my laptop away from me and when i asked to have her phone for a second she refused to give me it, yelling at me and asking whom i have to talk to so late at night that its so important. i woke up at 9 and found my laptop on the dining table and am posting this from here. i've removed my account from her phone through here too. what do i do/how should i handle this? the damage has been done, i'm not sure what texts she went through.

she is insane, went through some very private texts between my friends and i. in no way can i ever trust her again. im genuinely scared bc i think she's gonna scream at me when she wakes up.
