Having been divorced, I can say that I know the feeling of never wanting to be in a relationship ever again. I can relate to much of what you wrote. I'm not going to tell you that you should do anything differently, because even if you did change your mind right now, I know that it doesn't help to force yourself to get into new relationships when you're not ready.

Work and sleep ... that's a good plan, for now. Finding some cheap or free therapy would be a good one to add to it. Wounds need time to heal - it doesn't happen quickly. I'm still healing from my divorce and it's been 7 years. But, it DOES get better, I promise.

Day by day.... just take things day by day and try not to impose lifelong limitations on yourself while you're feeling this way, ok? Day by day... Hang in there
