Dealing with health anxiety

It's everday now. The thing i am thinking about starts happening. Like if i al thinking about having a heart problem my heart beat starts racing, feel tightness in chest, having pain in vhest and left arm. Its just one example i deal with wierd sesations in my body through out the day. Sometimes in throat, sometimes in legs, weakness. I'm fed up now. I am depressed too like feeling no point of life. Have been to hospital many time all test are fine but these sesations in my body doesn't let me live my life that i used to live before. Now it's at a point i where i am feeling that I'm going to die soon. Is there anybody else here dealing with the same.
