You have got several problems,
1. Gastritis- 37 years
2. High uric acid- may lead to GOUT
3. High BP
heart shivering- Cardiac cause
I think you should consult the doctors in following order-
1. Cardiologist- To thorough heart check up and exclude any heart disease
2. Psychiatrist- To treat depression because several symptoms may be this also. And now it is the second most common disease in the world.
3. Gastroenterologist- To treat the gastritis and prevent heart burn by proper medicine and their proper dosages.
4. Medicine- General health check up and treat high uric acid etc.
Best of luck.
