Thanks for choosing health care magic for posting your query.
From the description that you have given it appears that you are surely having anxiety symptoms. You might have noted yourself that your symptoms keep changing and are of transient in nature. It doesn't fall into any specific disease. You should visit your psychiatrist
who can discuss carious treatment options with you:
1) Cognitive behavioural therapy
2) Medications like escitalopram, mirtazapine
, venlafaxine, desvenlafaxine
will also help .
4) Regular exercise and proper diet will also help in long run.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
