Disappointed and Sad

In case none of you know I work in a homeless shelter, and Ive been here for about two years. I have met lots of people from various backgrounds, some with mental illness, substance abuse, ex cons, and people who are just down on their luck with no support system.

I befriended someone while working here, lets call him Bill. Bill and I became good friends while working at the shelter, although I was an employee and he was a guest we had a common friendship. He was the first person I told that me and my girlfriend of four years broke up. He told me his life story. I gave him money when he had none, and sometimes took him to Mcdonalds for a bite to eat. He eventually became a fellow employee at the shelter, and although he worked part time, he volunteered full time. A little while after he got laid off, talked about committing suicide, slinging dope, etc. I told him that If he did any of those things I will kick his ass, and meant it.

After returning from my weeklong vacation I was informed that he hasn't been at the shelter in a while, and the obvious rumor was that he was doing meth again, and staying at a tweeker pad.

If is is true, then I am saddened and deeply disappointed. He had been a good friend, and I do feel some form of guilt because if I hadn't gone on vacation, maybe he would have never gone down the rabbit hole.
