Why do I feel so numb all the time?

Dysphoria or the lack of ability to feel anything is a common side effect of depression. It's an awful feeling of emptiness and numbness that is usually tied to depression.

This depends on your personal experiences. Have you always felt this way? Did an event trigger this? It could be because you are experiencing something you don't want to feel so you've shut yourself down

Feeling numb can be due different factors. It can be due to a health issue or it can be due to a cause of a psychological issue that you are currently struggling on. Consider which is which and consult professional help if unsure.

Feeling numb is a symptom of stress over long periods of time. Sounds like, you need to find a way to bring down your stress.

Numbness can be physical or it can be mental (read: "psychological"). If you feeling physically numb (like not feeling heat when you touch a hot bowl of soup), it means that your sensory receptors are not functioning properly. You need to consult a doctor immediately as it maybe a sign of some form of allergy or something more serious like nerve damage. If you are feeling mentally numb (not being able to feel vivid emotions), you are probably under stress. In this case, you need to take an extended vacation or perform a creative hobby that turns the wheels of your creative mind. Or, do what I do, eat fruits. :)

it is possible that you feel disconnected from reality and unreal due to traumatic experiences or even anxiety and fear. Being numb takes all kinds of feelings away and it is likely we can feel that as a response from our body signaling to us we are feeling overwhelmed.

That's your minds way of trying to block yourself mentally from feeling mental pain. But it also blocks out other feelings as well. This happens when bad events take place where you just are not able to handle it.

Numbness can occur in depression (Anhedonia), Schizophrenia (During negative phases), PTSD and a variety of other conditions dependant on a number of factors. Numbness can also be caused by over use of certain perscribed and over the counter medications, illegal drugs or a combination of both.

You could feel numb all the time if you are bipolar and are at baseline. You could also feel numb, if you have disassociated yourself.

I find when am overwhelmed or feeling to many things at once my body automatically goes into shut down mode and I don't feel much of anything which can be dangerous if you don't feel anything you can end up in a dangerous situation and not realise it
