Hello Friend, Good that you are seeking a help. Depression will create all such negative mindsets even if everything is good around you. Don't allow such emotions to take control of your life. Don't worry. Such emotional imbalance is just like any other physical illness and can be treated through counseling session and few lifestyle changes. Take a counseling support directly or reach me online. I would prefer online for you as it will be easy and convenient for you to try.

Feeling low, having crying spells, sleep and appetite disturbances, and difficulty in concentration and attention are some of the signs of Depression. Consult a Psychiatrist for a detailed assessment. It is likely with medication and counseling the symptoms will improve. If you are feeling suicidal or hopeless consult a Psychiatrist immediately.
