Distract yourself and channelize the negativity and depression into something productive. Take your time and let it go. The more you hold on to it , the more miserable you'll become. Start loving yourself and see what difference it makes to your life
We all have this feeling from time to time. Just try and keep busy or try and do some gardening. If you have plants or flowers to grow and care for, they will give you some rewards when they have beautiful flowers which will lift up your spirits when you see their beautiful flowers and crops from your plants like vegetables or fruits. Chat to a trusted friend or meet up for coffee or lunch out. Friends can cheer you up sometimes.
