Why do I feel so depressed at night?

That can only be answered by you, my dear child because there are many possible scenarios such as: Do you constantly remember the things that make you feel stressed whenever you are about to sleep or Do you suddenly feel lonely because of the darkness? :D

That is a complex issue. One you may just be tired from the day. People who are already depressed use a lot of energy to do every day things like go to work or school. So you may simply be depleted at night. Secondly, you may be more lonely at night. If you come home to a empty home or are not emotionally attached to the people you live with (like roommates) you may just be noticing it more.) Lastly the brain is a complex tool. If you realize it or not it has it's own cycles and rhythms. At night the level of hormones in your body decrease. You brain is beginning your body for bed. So if you already struggle with the level in your brain you may be effected harder. That is the goal of all mental health medication is to bring those level back to normal. Unfortunately there is not a easy blood tests and trying different ones at different levels and combinations may be needed. We are always here 24/7 to talk to. So if depression hits you harder at nigh, try logging in.

you're alone with your own thoughts, it's kind of like locking yourself in a small room with a dangerous animal.

There are several different studies that suggest that your brain works differently at night if you stay up late and that sleep is necessary to sort of "recharge" it. How late are you staying up? Can you figure out ways to go to sleep earlier? Do you feel refreshed in the morning or do you still feel depressed? Also, are you getting enough sunlight during the day? Sunlight gives vitamin D to us humans which can also potentially influence mood. Talk to a doctor about this issue to get some more help and insight on what may be causing the depression and how to treat it.

Because at night you reflect on everything, good and bad, that haunts your memory. This is just what ive observed over the years but there may be more reasons as well.

You feel more alone at night, because you feel like you're the only one who's still awake. You have more time to think because the world is resting and quiet. It feels like it's just you and your feelings.

Feeling depressed at night is a very common problem so remember that you are not odd or alone in feeling this way! You may be depressed because it makes you feel lonely. You may become depressed because the night's silence leaves you to think about the things that upset you. I find music to be very helpful in keeping the mood positive on a quiet night.

It's possible that since you're unwinding down from your busy day, you're being less distracted which gives your depression time to affect you more and your thoughts to run wild.

Throughout the day, most of us are so busy rushing around, and working, and interacting, and surfing, and shopping, and doing stuff, that our 'inner self' gets very little opportunity to express itself. The inner self doesn't give up trying to communicate with us, and its best time is when things have finally calmed down a little bit, and there's a bit of peace and space, ie, bed time. Night time is quiet time (at least, relatively), when all the bustle of the day has gone. A lot of our uncomfortable, difficult emotions surface at night, simply because the distractions have disappeared. They are actually there the whole time, just we aren't paying attention to them.
