Feeling helplessness. Am i beautiful?

Your symptoms are suggestive of Depression. The depression could be either secondary to such common ailments as mild hypothyroidism, borderline diabetes, Vitamin D or Vitamin B12 deficiency, or several other mineral and vitamin deficiencies. It could also be secondary to a sedentary lifestyle which could bring about hormonal disturbances. Sometimes the exact cause of depression may not be identifiable, in which case we presume it to be primarily psychological. In any case, it appears you have very good insight to your problem. This points goes in your favor in that you are more likely to seek professional help and stick to the treatment regimen. Please consult a psychiatrist in person and get yourself examined. You may also request the psychiatrist to kindly rule out the other medical conditions that I have mentioned. Once the diagnosis is established and treatment started, you will find improvement and even probably a sea change in your moods within two to three weeks. You will start smiling and laughing once again. But please do not neglect such things as Pranayama, meditation and a daily walk in your day to day program.
