Hi I would advise you to take help from a psychologist Consult with me or any psychologist for therapy and counseling Tall about what stresses you out about the social situation All the best

Having a healthy social life is life skill, many times we are not aware of this may be because of past experiences. There are always 2 perspective to know who we are,  1 who you are in your perspective and who you are in others perspective,   both are equally important, Reach out to people around you whom you trust and ask for feedback about you, do some introspection.  If you feel help is necessary talk to counselor near by or online.

Agree with dr Bhat

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 counselings the symptoms will improve. If you are feeling suicidal or hopeless consult a Psychiatrist immediately.
