Hey I'm a 21 year old guy Usually i had mood swings quiet often now they've  transformed into 2-3 min outbursts of anger on typically anything with no content to make me angry For ex- I call someone two to three times if they do not respond or come late im found extremely furious on the verge of exploding and i keep using foul language After its done i usually don't feel like eating until the next day or so (like for the next 24 hours) And also i have this thing Going on where I'm finding myself avoiding my friends i feel like i dont want them at all but its only for a brief period and i go back but this thing keeps happening every few months on a loop during this time I'm very depressed and irritated I'm usually a humble guy i dont know why this is happening to me Can anybody please help me out on this? Thanks.
