Period of intense anxiety and depression

Hello, im currently going through a major rough patch that has disrupted my life. Ive had this happen before, with very clear triggers, but this time it just seemed to have come from out of nowhere. Anyway, i guess i could use some people to talk to and share experiences and advice. I cant sleep, eat, think of anything else except my problems in life. I havent had any relief since this started about 2 weeks ago.
