Reading my previous posts got me thinking: why do my emotions fluctuate so much?

I self-pity, self-blame, encourage myself to be strong, am positive, am depressed, am suicidal, am at peace, am weepy, all in the same fortnight.

Am I a weakling who tries too hard to be strong? Or a steady person with lapse of strength and self-sustenance?

Or am I just being a regular girl? Why would anyone want someone like that? Why would Dave even want me? No wonder he doesn't want me.
