I'm extremely irritable. What gives?

I don’t get it! Everything is looking up (two potential jobs coming up, been eating well, walking tons, enjoying beautiful, sunny weather, haven’t had a drink in almost 2 weeks…) but I’m feeling like crap.

I suppose it could be hormonal (but it shouldn’t be)? But I don’t want to feel like this. How can I get over it? It’s been a few days now… no amount of walking, or eating well, or playing in the sun is helping. Suggestions? Please?!
