Feeling depressed when you don’t have anything to be depressed about is the first thought your brain is signaling that something is wrong. It’s great that you listened to that voice.
Sometimes we don’t know why we are depressed. We can’t pinpoint a singular reason that could be making us feel low, numb, or sad. Even when nothing is wrong and life feels good, we can still get depressed. Episodes of depression can come and go. Why we have depressive symptoms is often out of our control.
The reason we’re depressed could be related to our brains. This could be past trauma, genetics and family history, or how our individual brains work. Or the reason could be our bodies. For example, we might be taking a medication or experiencing an underlying physical health condition.
If you are feeling depressed but can’t identify a specific reason—like a major life change, grief, or a difficult situation—it’s worth investigating and reflecting on what might be going on.
Depression and our brains
Our brains can play a role in why we feel depressed when everything seems okay.
For example, if you live with depression, sometimes depressive episodes can start without warning. There doesn’t have to be a specific reason why. It’s like when you live with a chronic physical condition, sometimes things that we don’t see or know can trigger illness. It’s the same with a mental illness.
Also, if depression or other mental health conditions run in our families, then we’re more likely to experience depression. This is something that is out of our control and not our fault. Knowing that we’re more susceptible to experiencing depression can also help us learn what to do or who to talk to when we feel depressed.
Past trauma can also resurface in subtle ways. While on the outside we appear fine, when we encounter our triggers, it can knock us off base and make us feel depressed. Trauma changes our brains. So, while nothing in our lives at the moment is wrong, it doesn’t mean we can’t feel depressed because of past traumas and memories.
Our brains are complicated places, and everyone’s brain is different. Even when everything seems okay, we can still feel off or depressed. That’s okay. Once we recognize how we are feeling, we can begin to figure out the steps to feel better.
Depression and our bodies
Sometimes depression can stem from changes in our bodies. It’s a fact that depression can co-occur with physical conditions. [1] Depression can also lead to and result from different physical conditions as well [2]. Physical illnesses, or even a change in medication, can lead to depressive symptoms.
Could a physical condition cause depression?
There are many physical health conditions that increase the risk of, co-occur with, or cause depression. Chronic illnesses, autoimmune diseases, heart disease, thyroid disorders, and even diabetes are examples of physical conditions where people often also experience depression. And there are many more than that! [2] Even the common cold can make us feel bad mentally before we get any physical symptoms.
If your depression seems to have come from out of nowhere, then it might be a good idea to talk to your doctor. They can run tests, ask questions, and help you figure out if a physical health condition might be the culprit behind your depression. Making sure you “rule out” these other factors is important for making sure you are treating the real root problem.
Could medication cause depression?
If you changed or started a new medication, then it’s possible that one of the side effects could be depression. For example, allergy meds, pain medications, birth control, blood pressure meds, and antiseizure medication all have depression listed as a side effect. [3]
Think about whether you’ve started taking anything new lately around the time your depression symptoms started. This could be a reason you feel depressed while having nothing to be depressed about. It’s a good idea to check in with your doctor and tell them about your symptoms—especially if they prescribed the medication. They can help you safely taper off the medication or find an alternative.
Is it Depression?
Episodes of depression can come and go, but trying to figure out what is going on for you is the first step. Taking the time to reflect on your experiences and your health can help you discover what’s really going on. And this is an important step toward feeling better and improving your overall well-being.
If you don’t think it’s coming from other medical conditions, then it’s a good sign that the depression is coming from your brain and your life experiences, and mental health support is the right next step.
