i thought that i was finally getting happier/ coming out of my depression and just being like a normal teenager for once. im just soooo sick of being constantly down and often suicidal. ive been feeling better for a couple of weeks now but i found out today that someone who came into our shop this morning tried to OD on the medicines she bought from us. even though i know its not my fault i still feel guilty and i just get the feeling that this is just going to send me spiralling back into depression again, something i definitely DONT want. any advice?
