Hi, Such feelings can really make you feel numb. First you need to find the energy to contact a close friend or relative. In order to do that, you can start by noting down atleast 3 things in life that are worth living for. These can be anything( spouse, children, chocolate, love etccc). Visualise being surrounded by these positive things in your life and encourage yourself to contact a loved one. If this feeling persists for a longer duration and brings your life to a standstill, please seek psychological help asap.

Feeling sad consistently, poor social interaction, fatigue, poor interest in previously liked activities are signs of depression. Depression can be treated and controlled with medicines. Consult psychiatrist.
