I am sorry you are feeling this low. Please seek professional help immediately.please see a psychiatrist in person at the earliest. Talk to your family and friends about how you are feeling. Feeling sad, disinterested and hopeless could be a sign of depression. You will need an evaluation and Treatment which may consists of medications as well as psychological therapy. Don't lose hope.a lot of people are able to come out of it with proper treatment and support. Thanks Regards Dr Ankita Mishra

It's really a tough situation. Do take help from your relatives/ friends and consult a Psychologist. These symptoms should not be ignored as these are suggestive of depression. It could be treated.
