So Iv has depression my whole life and it hasn’t gotten better it got worse and now I deal everyday with the struggle of getting dressed and taking a shower and just leaving the house. Recently one of my really good friends died from drugs and I have to go to her funeral tomorrow and I can’t handle being anymore depressed then I already am. I’m not suicidal I’m just fucking so depressed every minute I’m awake and I need tips and tricks from you guys to get me through hard times! I know it’s not going to just go away I just need tips to get my mind off of the sadness!
