Mood swings and depression

In the past week or so I’ve started going through an episode of depression. Been having a lot of moments where I can’t help but just cry. It’s almost like I’m fine one moment and the next I’m crying. I have had this long enough that I can deduct the causes and such but it still doesn’t help that I feel like crap. I am on medication but there are just times where it’s not enough. I can’t help but apologize consistently to my boyfriend because I can’t help but feel like a burden and like I’m being dramatic. I talk things out with my bf, best friends, and family. Anyone else struggle with a feeling of guilt for feeling/thinking the way you do?
