India is the 2nd most depressed country in the world with millions suffering silently. From the symptoms that you've mentioned, the chances of it being depression ars high. I would recommend that you schedule a counselling session to explore her issues in detail for a formal diagnosis. Additionally, you might also need to visit a psychiatrist in case medication is required. Her issues can be easily overcome through psychotherapy and medication (if needed).

Hi, you can contact me for an online appointment and we can explore this narrative together

It looks like that she is upset about something or someone.. She is not able to accept or to come in terms with the issue.. Because of her age, a d the expectations are not met, she feels life isn't worth, if what she wanted is not met.. I suggest you to fix an appointment on behalf of her,.. So that, what she is not able to do with you as parents,  she might be able to share and discuss her feelings...

Hi... These are your observations which aren't enough to make a Diagnosis/Prognosis. You will need to consult a Psychiatrist to get a diagnosis. But in this case, I believe she is undergoing some psycho-social turmoil. Considering her age (22), it may be something related to her career, relationships, family, friends, etc. In any way she will need a good Therapist/Psychologist to first open her up and then help her overcome her issues. But her willingness to undergo therapy is very important.
