feeling overwhelmed and tired

My life has been very busy lately and I am having a hard time dealing with it. My mood is generally crashing down when I get home and I am dismissing my emotions to focus on my daily tasks better but it just feels like sliding them under the carpet - they are still there. My sleep schedule is not very good and I think it also have and effect on my daily life. I generally avoid sleeping just to spend more time with myself. Cause social occasions overwhelmes me after some point and when I get home my personal time is very limited and I crave the time I spend on my own and I am trying to win it back by cutting it from my sleep but it's not good for me either.
