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.

I understand that you are going through an emotional turmol. This is commonly observed during the onset of adulthood due to various stressors - interpersonal relationships, career, financial or a combination of these. I know that crying is considered to be helpful in venting out but that is not true for all. Different individuals have different ways of venting - talking it out, physical activity, introspecting, humour. However, a desire to cry and unable to do so with a deep sense of sadness or hopelessness or helplessness will need counselling or medication or both depending on the severity of the depression. For starters, you may approach a counselling psychologist. In case, there is not much response over 3 months of counselling or if the symptoms increase, you may consider starting temporary medications from a psychiatrist (Allopathy / Homoeoapthy). Homoeopathy medicines are safe i.e without side effects, treat the disease from the root cause thereby giving long term relieef. For any further queries, you may contact me via Practo online portal.
