<bot>: Hi, From your description you are having depression. Depression can occur due to many reasons which need evaluation. Try to do daily aerobic exercise and involve yourself with friends/family members. If problem is very severe and leading to frequent interpersonal problems, then for assessment and treatment, you can visit specialist like psychiatrist. I hope this information has been both informative and helpful for you. Wish you Good Health.
