Why is life so depressing

Exhaustion affects our mood, our energy levels, and our cognitive functioning. The problem is, depression can cause sleep disturbances, so it can become a vicious cycle. Speak with your therapist about ensuring proper sleep hygiene, learning cognitive behavioral strategies for managing insomnia. From the moment we are born, every nice thing that we experience, a moment of hapiness brings a depression afterwards because we miss the thing that made us happy.

Hope this helps and don't get depressed!
