Severe depression, loss of concentration

I appreciate your efforts to overcome the depression. Physical activity does matter to handle the depression. Also, you need to understand the reason behind your disinterested attitude or sadness to handle  it holistically.

Seek a professional support. Consult a psychologist.

Some non-pharmacological measures to overcome depression are as follows. 1. Practice mindfulness. It involves focusing on the present moment. 2. Listen to good happy music as food for the soul.

Don't skip meals. 5. Boost your vitamin B by supplement. 6. Include omega 3 fatty acids in your diet through walnut, flaxseed, fishliver oil capsule. 7. Stop negative self talk. 8. Keeping busy is an effective way to overcome depression. 9. Connect with friends. Social support is absolutely essential to depression recovery. 10.  Forgive others. 11. Regular exercise. 12. Keep faith in yourself. 13.  Pick up a former hobby. 14.  Express your self creatively through music, art, and writing.
