Hi my friend (20nb) has been locked in their room for a few days now like not reading texts avoiding our other friends (who are also our flat mates) and only leaving their room when we are not there to go to the bathroom to shower and go to work. It’s super odd and unlike them to do this as they never have done it before while living with them for the past 2 years, I’m worried they could be possibly a danger to themselves, as it’s day 4-5 since this has been happening. The last time I’ve seen them was 2:35am after we were hanging out with our friends and seems like they were genuinely happy. The thing I’m most worried about is them not eating or drinking when they are home. I feel useless as I go through bad depression episodes myself a lot but I just feel lost and stressed, and I just need advice
