Hidden Depression and No One to Listen

I’ve had pretty bad anxiety for quite a few years and am on medication for it, but sometimes things get so bad it’s hard for me to handle. I don’t know if it’s right for me to say I’m suffering from depression because I’ve not been told so from a doctor. I’ve been having a hard time recently, and I’ve not been able to perform the tasks I need to, or that I should want to, and I just want to cry a lot of the time. I’m a college honor student and I can’t even do my work and I know I’m letting my professors and my family down. It’s so hard for me to seek help from people, but it seems every time i get the confidence to we end up talking about the hard time they’re going through and, it makes me feel so guilty for trying to put my problems on others. I don’t know what to do anymore; I can’t keep doing this, but I can’t seem to get help. I’m suffering financially right now so I can’t see a doctor, but no one around me sees that I’m hurting. Does anyone have any advice so I can help myself even a little?
