Since October I've felt incredibly low. The lowest I've ever felt. I could barely bring myself to get out of bed and go about my day but somehow I did. I spent hours on my own just crying over nothing. I started to feel better on Christmas Day and up until last Wednesday I've felt elated...almost like I was on a high. This weekend I've felt the 'depression' coming back. My house is a mess, I'm not sleeping, I'm just sitting doing nothing and barely talking to anyone. I'm scared that I'm going to get to my lowest point again and worrying about how long it will take me to feel happy again. How can I stop this and build myself back up. I feel like I can never just be 'normal'. I'm either really high or really low. I hate feeling like this.
