What helps when you’re extremely depressed and what once helped, no longer helps? I legit just feel like giving up and end it all

I’m feeling this way the last 2 weeks and can’t get out of this rut. Usually it comes and goes but it’s not going this time. I’ve avoided seeing a doctor but I think it’s time

Nothing helps anymore I just like to drown myself in a pool of negative energy and suffer through it

Help someone else any way you can.
