It is clear from your mail that you are going through a difficult phase. The symptoms of fatiguability, lack of energy, lack of focus etc point towards depression
. It has been going on a few months now, so clearly you need help.
You need to meet a psychiatrist
and obtain treatment. There are many medicines available that are beneficial and have very few side-effects. You may also benefit from psychotherapy
(talk-therapy). However, considering that you have a lot of physical symptoms and of significant severity, you will almost certainly require medications. The medicines will make you feel better and you can later alongside that undergo psychotherapy. In your current condition, psychotherapy alone is less likely to work.
At the same time, as mentioned by siva prasad reddy, do not hesitate to approach close friends and relatives for help. Speak with them and discuss your situation. Their support will help you tide over this tough period.
