I Battle Depression and Anxiety

Does anyone else get very depressed during the summer but then are perfectly fine during the winter?
Because I have been experiencing a lot of symptoms of GAD and Panic Disorder for the past couple years, I get super tired and irritable, and lately I've been noticing how depressed I can get lately, especially during summertime. I'm getting a little bit better, but today has been a great day for me comparing to the past couple weeks I have been through. It's scary when you legit consider suicide... I'm good now, though. :-)
