Is it normal to regularly become sad for no reason?

I was sad all the time until I started treatment with meds.

I think its pretty normal for me but ive always had depression/anxiety so its normal to me. But if its new to you, talk to a doctor.

Depression.

I have this though, I get extremely beaten down emotionally easily, but I have suspected depression in myself quite a few times. Was even told by a therapist once that I might suffer from depression but it was never looked into any deeper and I haven't bothered either. There's definietely treatment though if you have it really badly and struggle hard with managing it on your own.

No.

You might have depression, bro. Do you snap at people a lot?

Get yourself some meds. SSRIs are pretty sweet for feeling generally good.

Blood sugar?

Probably bipolar disorder.

I have something similar but its more like sometimes I'm off. I cant really explain it but I'll be really hype for a few weeks. Ill be feeling awesome and then a week or two ill fill like something isnt firing off ill stutter and lose coordination abit.
