Last weekend, I snapped out of a five month deep depression. Five months of gloom, defeat, bed rotting, suicidal ideation. Then I woke up on Sunday and it was just gone. I had no idea I could just snap out of it like that. The shitty situation that brought me down in the first place is still there, but now I have the motivation to change it. I wish I knew the trigger and could share it with you, but I can tell you that all those bad feelings won't last and you can and will feel like yourself again. So don't give up on yourselves. Maybe this will help:
