First off show your power. Being able to cope with reality will make you a very strong person. And you being able to be there for your family and friends will make your personal relationships and bonds grow a lot. As hard as it is to do or say you have to try to get some good from a bad situation. You can definitely gain inner strength why'll helping yourself and others here.
That's kind of what I've learned in my experiences. I've lost 4 friends way too early, first being when I was 17. The worst is probably when my friend of 23 died of heart failure, don't do drugs people. Same kind of situation actually. I was going to pick him up to go get some breakfast, I walked in and he was out on the floor dead, with his 1 year old baby crying next to him. I think the worse thing you can do is ask yourself if you could of changed anything, you can't. It has nothing to do with weakness in yourself but more of it happened, we aren't god, it's just that simple. I'm truthfully afraid to speculate what losing a parent feels like but with my friends now I just smile. At first I did cry but that's almost natural, I do now too but it's tears of joy. I just think about em and start smiling and it brings tears to my eyes. I think about who they were and what we had I don't think about them being dead or dwell on what happened I just realize I had the chance to know them and be apart of their life and have them apart of mine and for that I am honored, and blessed. I don't really know what all of this means but when dealing with what happened to me I didn't make a thread about it, which isn't a bad thing, but I did read about other peoples situations and how they dealt with things. It gave me ideas of what they did but then it also sparked some from me so it helped reading others experiences. So I mean I guess I would say you're on the right path, just keep moving. Sorry if this makes no sense I was just typin away randomly.
