Prayers when health is at risk?

Jai Siya Ram everyone. I find out sometime this week or next week if something is wrong with my heart. It’s been a very tough last 2-3 weeks, and I keep thinking about death and how my family will feel if something is wrong. How I have not done anything significant in life and if something bad were to happen, the after state that would be. I even skipped a day of shower today, and don’t feel like doing anything. How can I pray for good health and hope that the results are fine? Are there any gods that can help me here in feeling positive, and as crazy as it sounds, just making sure nothing is wrong with me?
