I can understand your concern.
There are a lot of probable causes for these symptoms like stress, fear, anxiety, dietary deficiencies, thyroid dysfunction, hormonal imbalances, etc.
Have a high protein diet, lots of greens , vegetables and fruits along with one capsule gibkoba-m once a day after food.
That will take care of the dietary deficiency part.
Get your thyroid level evaluated.
On an empty stomach in early morning get a blood test done for T3 T4 and TSH.
Consult a physician with reports for further management.
