Hey Adam,
Here are my thoughts on 'the future': it changes. It's not always going to be as bad as you feel now, and it's not always going to be as good as you felt after you came out to Max either.
I'm sorry to hear that your depression is getting worse and that things aren't going well with your friends. I'm not them, so I can't know what they intended, but sometimes these things feel like a bigger deal to the recipient than they are to the person who said them. They may not have intended to be hurtful, even though they were, and I'm pretty sure if they knew, they wouldn't want you to feel the way you are.
At any rate, I know it's easier said than done, but you shouldn't let their actions or words impact your thoughts about your self worth or the meaningfulness of the future so much. I know that I don't know you, but from reading your blog I can tell that you are a sweet and caring guy.
And that's something that isn't going to change.
