Depression/Anxiety

I’m a first year college student in my first relationship (8 months) and lately I’ve been extremely emotional. Not a normal occasional emotional but like I don’t have control over my emotions at all. I’m oftentimes very down and sad for no real reason it just happens at random where I’ll start bawling crying & feel really shitty out of nowhere. I feel like I may be suffering from depression but I’m not sure & I also suffer from social anxiety (have for as long as I can remember) but lately I feel anxious constantly which also messes with my mood. Has anyone gone through this & knows what I’m talking about? How did you cope & get over this?
