Hi Tumnus! I know exactly how you feel. I have some days where I'm just sooo happy. Nothing will really happen to me these days but I'm just happy, not really for any external reason. Then the very next day I wake up and I'm just BLAH and then everything seems to bother me. What helps me is when I am in a BLAH mood, I tell myself that it will pass and my mood will change. Your bad mood isn't YOU, rather it's just a mood. I try to put on my happy face despite everything. If I'm trying to be happy when I'm sad, sometimes it works and sometimes it doesn't. It's easier said than done to just BE HAPPY. For me, I try to do my best to give love. If I expect people to love me sometimes that love will not find me. But if I go out of my way to just love people then love is its own reward. So I smile and say hello to strangers even if I'm feeling bad. If the other person doesn't smile back, oh well. If they do, sometimes it's their smile or their saying hello that will just brighten my day and turn the tides for the better. But hey, you'll be okay!! By the time you're reading this you'll probably already be in a good mood! If not, well, oh well, you'll get better. Read a book or something inspiring. For me, reading will either help me improve myself or it'll distract me. Some good websites are Happinessinthisworld.com and also ZenHabits.Net. Good luck, my friend. I hope you are doing okayyyy!!!!!
