You no need be worry about, from your description I see no any seriously health issue. Very probably malaise
, asthenia, gastric disturbances you have due to hormonal
, microelements imbalance. In your case you need adequate and properly diet( rich in vitamins
and microelements, daily fresh fruits and juice) regularly at same time minimum three times per day, sleep minimum 8 hours preferable go to bed at same time, don’t forget about moderate short duration physical exercises which will help refresh your blood in oxygen
and will increase your general tonus. Also will be good if you will make appointment with Endocrinologist
to check your hormonal level and general biochemistry.
