Inability to sleep at night: Common with depression?

Based on what I have experienced and observed, yes, it is common.

Some people become like emotional vampires, unable to face the sunlight.

That being said, I think a great many people, myself included, have undergone periods of disturbed sleep rhythms, especially when under great stress. Not from depression, simply being overwhelmed.

How long have you been like this? Anything especially intense going on in your life?

And to be clear, I am not a professional psychotherapist. This is my personal opinion. Clinical depression is a serious condition and needs professional attention.

Something you might want to try if you're feeling depressed, an episode of my YouTube channel, "From Recovery to Discovery":

Yes it is very common. There are some medications that can help - but your doctor will decide what may work best for you.

Very common and something I deal with as well. My wife's job has us up at 4:00 am which makes those nights a real challenge. I have tried some sleep remedies to get myself to sleep on those difficult nights. Definitely talk to a doctor before doing any of those however. It really sounds like you are dealing with depression though Scott be right about it being major stress or being overwhelmed. There are a lot of suggestions we can probably offer but the best one is to talk to your primary care doctor and see what they say.
