When Can I Snap?

When the same onslaught of problems threaten to take me down, and I am still not completely healed from the past, when is it OK to freak out and break down? Stop telling me I got this handled, reality is I feel the control slipping. Why can't I just whine for a minute? I'm not the type to tell everyone everything that is wrong, and I'm not the type to publicly wallow, I guess because of that people turn a deaf ear. I'm not saying people don't have it worse than me at all, but why does it always become something like that? I'm stronger than you because all of this happened to me is not comforting. Everyone is different, and we all have our different challenges. I don't understand how being considered a strong person, who has been through many different situations, means I should be blown off and ignored when I'm hurting. People that whine non stop annoy me, I strive to not be that way, I am generally a person who worries and I'm not the most positive, but I'm working on that. I have issues with blaming myself when things go wrong, and as much as I'd like to think I'm above judgement, I am hurt by criticism much more than I should be. I know I have to work on myself more because I can't change what people say, but it would help if they were nicer.
