feelings of self hate

I have been trying my damndest to keep the feelings of anger and self loathing at bay. Throwing myself into homework, my job or just hobbies but the thoughts of meaninglessness wont stop digging into me. All I can do is keep myself focused on my daily tasks and try to meditate. Saddly though my appetite for junk food is probably not the best remedy for these feelings. Actually that may be why I'm sinking into this...
