Hi, welcome to the forum! You'll find a lot of support and encouragement here. :)
It sounds exactly like you have anxiety. And no, you're not crazy. When we get anxious, sometimes our thoughts aren't rational. You could even say that they are not YOUR thoughts at all.
What is happening is that your body is reacting to a misfired "fight or flight" warning. For some reason your brain thinks you are in danger, so it sent out a distress signal to your body. Now your body is trying to gear you up to have the endurance for a fight or to run away. Since you aren't in danger at all, it's very alarming to experience this.
I like to think of it like this: Your thought process is an army, and your brain is the general who has asked it to find the danger. Your thoughts run all over the place, but can't find any danger. They come back and tell your brain, however your brain is intent on finding danger (there is a warning siren going off, after all), so your thoughts go to anxiety for help. For the record, anxiety gives terrible advice. It's never correct, and it just scares the army. The army brings this intel back to the general who doesn't think it sounds right at all, so the army goes back to anxiety... and repeat.
I know it's a silly analogy but that's basically what's happening. That's why you have strange ideas about
what might be happening to you, even though your rational brain (the general) knows they aren't true. Sometimes it can be hard to distinguish where these thoughts originate (since they are all in your brain), and you become scared that you're going crazy. But you aren't... it's just anxiety talking, and anxiety is a liar.
You have a few options on what to do. You could go see a psychiatrist and possibly get a medication to make your symptoms go away. I know this may sound like a daunting option if you've never been to one before, but psychiatrists are just like regular doctors. It's their job to help you get better. Plus, the relief you feel once you get rid of the anxiety is priceless. You could also go to a therapist to learn coping skills to help deal with your anxiety. Many people use both of these options. In the meantime you can practice self-help, which is basically learning coping techniques and other useful exercises to do on your own. There is an extensive resources section on this forum to help you get started.
It also really helps to talk to people who are going through (or have gone through) the same sorts of things. Coming to this forum will definitely help ease your mind and help you get on the right track to recovery.
Take care, and post as often as you like! We are all here to help, and will chime in at all sorts of times. :)
