Why do I always think I'm dying?

Severe anxiety, in my opinion, over one's mortality and difficulty reconciling the fear of death with acceptance to feel secure.

It could possibly stem from a fear of losing the things close to you, or having a fear of missing out. With certain practices, i'm sure you'll be able to overcome this feeling of dread.

I don't have much information to answer this to you but im sure the therapist from this site will know how to response this and will help you with all the things you need

Sometimes people feel this way. Have you tried reading the depression guide? It would really help you.

That sounds like you are really depressed. You should talk to a trust-able adult about this. I suggest talking to a therapist.

It may be depression, Depression can make you seem ill and make your body shut down so that might be the cause.

Because you are clearly depressed. These thoughts cab also arise out of existential wonders and what not.

You may be experiencing hypochondria or neurosis, and misinterpreting symptoms that may or may not be there or as severe as they seem

Is it a medical situation, if it is please go seek help. It may be a mental thing too, maybe see a professional therapist for help. You'll be okay.

Intrusive thoughts like these can be common for a lot of people, although if they are a daily reoccurence, you might develop anxiety. If any of us would say "I'm dying", well that would be true, since all of us are slowly marching to our deaths. And if you are experiencing any pain in your body or any discomfort, the thought "I am dying" can be that much reinforced. On the other hand, would it be true if we said: "I'm living"? I'm currently not dead, so I must be living then. My body is in pain, but I'm still living. I'm very anxious, but I'm still living. . . We don't usually pay attention to the wonderful fact of our life and we tend to obsess about our deaths. That's natural since we want to survive, we want to avoid death, so it's natural to ask ourselves if we are dying. The problem occurs when we do it too much and we forget that we are indeed living! I guess it's a good exercise to remind yourself that you are living when everything seems to be ok when nothing is wrong, nothing is hurting and we are in a good state of mind. That way we have an opportunity to see what is here and gratitude will naturally emerge in that moment.
