I have dealt with depression on and off for about 4 years, with my most serious case happening about 6 months ago. I can feel it getting this bad again, and my boyfriend used to make me so happy and help me a lot, but now I feel like it's getting in the way of our reltionship and I can't properly interact or talk to him because there's constantly this barrier, of which I do not know the cause. I literally have no idea why I'm so down. Help?
