What can I do for lower eyelid fine lines/wrinkles caused by crying? (Photos)

There are a lot of options to treat this. The main issue is that when you cry you likely irritate the skin in this area and this leads to some swelling.
First thing is first you need to get your depression under control. This is paramount. There are also many options to treat depression these days. From therapy, to exercise and even to medications that are very successful. This will likely make a significant difference in your lines as well and maybe you will not need any surgery at all.
I recommend getting the route cause treated and then if the problem persist you could consider other treatment options. If anything, in some one your age, I would recommend being conservative with something like a light laser or chemical peel. 
Hope this helps.
Best of luck,

Fractional laser is an amazing and highly effective treatment in our office. We use the laser treatment to help with acne scars, large pores, fine wrinkles, tissue collagen loss, scars, sebaceous hyperplasia, active acne, and for brightening dark pigmentation. Although there are very strong fractional lasers such as CO2 laser, we use lighter treatments for corrective skincare and maintenance of results. Our Thulium fractional laser, clear and brilliant laser, and Ultra Thulium laser are excellent options in our clinic. We also perform CO2 fractional and erbium depending on skin tone and tolerance for downtime. Patients do have to use a Melarase cream before and after treatment to help further reduce pigmentation after laser. Melarase AM, Melarase PM, and Melapads can seriously improve surface sun damage and UV related pigmentation. Dark spots can improve with these treatments. I recommend fractional laser for incisional scars as well, especially after plastic surgery.
