You mentioned you struggle with depression, are you on any medications for that? Often medications used to treat depression actually decrease one's interest or desires for sex.

You are a female correct? If so you may want to have your hormone levels checked. Often sexual desires come from our hormone levels. And even depression can come from hormonal imbalances too. I learned this by accident when I had to take a drug after having surgery for endometriosis that changed my hormones so I would not experience having my period. Well, unfortunately this drug decreased my estrogen levels so dramatically that I sunk into a completely debilitating depression. Then I had to get treatment to restore my hormone levels and that slowly brought me out of the severe depression.

So, my suggestion to you is to have blood work done to test your horomone levels. Also as I mentioned, some of the medications used to treat depression significantly reduce a person's sex drive.
