I hope you’re not being serious…As dismal as life can be at times there are so many good aspects to it that the bad things almost don’t matter. If the things that used to give you joy do not have the same effect do other things. Take the bad in stride and find different ways to look at your problems can really effect your perception of things and in turn that should improve your mood. Lastly, fixate on the positives. Even if you have had tons of shit thrown at you on a particular day thinking of a couple of good things about that day can keep those dismal thoughts away.
Trust me man…I’ve been there and still drift there every now and again but whenever I go too deep I remember that I’m better than to be subjected by my own thoughts and my current situation. There’s no reason why you can’t shake off whatever it is you’re feeling.
