Anxiety is controlling me. Help?

Ive never actually had anxiety this bad. For the first couple months when it first started it was bad but I feel like this is on a whole new level. I lost my grandmother in January to cancer and it just feels like theres always something givin me anxiety attacks at least once a week. Im just so tired and want to feel normal again but its so hard. Im mostly anxious over health stuff with people I know and myself and it just sends me spiraling even if its the littlest thing wrong. Does anyone have any suggestions on what to do or techniques to help combat this? I want to get my life back
