I've been around the block a few times and I just wanted to say... living is not all it's cracked up to be but I'd rather be living than face down in some dark alley more dead than alive.
Drinking and drugs don't make it better they just stand a happy fave in front of the bad stuff. Remove the happy face and the issue you are hiding from will still be there waiting for you. You will either have to deal with them or die avoiding them. I repeat I'd rather be alive even if I'm in emotional pain. The pain can be dealt with using therapy and exercise.
