It very much could be related to peri-menopause. I'm a bit confused why your doc would immediately put you on an anti-depressant rather than trying some other options. That's an extreme thing to do and kind of skips easier options.
For me, I was on birth control because I have never been regular my entire life. I had been "fixed" as well after having my triplets (5 kids) so the only purpose for the BC pill was to keep me regular. After a few years I was having emotional problems. My doc took full blood work and a physical to see where I was at. Although my blood work didn't show that I was entering peri-menopause, my symptoms said otherwise. Blood work doesn't always show hormones rising since they go up and down so much and when my blood work was taken the hormones were down that day and I was doing ok. But the doc wanted to see where my vitamin and mineral levels were at as that can cause problems as well in women our age.
I was 39 when I had my triplets. I was in my early 40s when I started having emotional problems, around 42 or 43. I've had depression and anxiety so I knew the difference.
After all the blood work, my doc did one big change. She changed my BC pill. The pill I was on was the kind that gave hormones for 3 weeks with each week being higher doses than the last, then no hormones the 4th week as usual. The new BC was a type that gave the same dosage of hormones for 3 weeks straight and then off a week. My doc, a woman, felt that at my age my hormones are floating up and down enough as it is. Why have a BC pill that added to the problem.
Next, she had me take what she called a "vitamin cocktail". It would be different for each woman overall. For me, my triplet pregnancy drained most if not all of my calcium supply so I am on high amounts of calcium, which helps stay off my arthritis in my thumbs, which is one of the first places you'll get it. Most women don't get enough Vitamin E so I have a good dose of that. I take a high dose of Vitamin B12 for energy. Also, I take Centrum vitamin at bed time. These vitamins help balance what I'm missing and does make me feel a bit better.
A few years later I started having some more symptoms again as our bodies change and we added Black Cohosh daily to help with mild hot flashes and a touch of moodiness, which helps.
I really think you need to get yourself checked for your hormones. Putting you on an anti-depressant seems to me to be jumping the gun. I think you should try to level out your hormones first to see if that's an issue first, which sounds like it surely is. Ask for blood work, see what you're lacking, fill in the gaps, and even ask about the proper BC pill to go on for the hormones to balance out. You may see better results than an anti-depressant. If you're taking an anti-depressant and don't need it you may not get the results you want. Don't be afraid to go with another doc as well!
