I appreciate you bringing this up and talking on it. Just know that you are not alone, and you never will be. Most of us on here has experienced those same thoughts about suicide, and personally I think it is normal. Me personally, I wondered what would happen if I would pass, and who might come to my funeral. I was in a dark place once upon a time where I was over a thousand miles from home with a loaded rig, in tears and by the grace of god I was shaking to much to do the shot. I reached out and spoke with a friend/using buddy, and even though I didn't OD that night I continued to get high. So with you speaking on it does really help the process in healing.
There are tons of people here that only want the best for you. Even if people in 'real-life' don't care, just know you have people here that do.
