It appears you are suffering from anxiety. There may be an element of depression too. Please attend pranayama and yoga classes, and also try to learn meditation. You may consider joining Ravi Shankar's Art of Living course. At the same time you may consult a psychiatrist in person, and explain him your problem. You may also ask him to get your blood tested for

vitamin D and Vit
B12 levels. The psychiatrist will advise you whether you need any medicines. Take care
