trigger warning depression

so I need some advice ladies. I have been handling everything very well with my life lately but for the past week I feel like I have a brick on my chest constantly. I haven't stopped crying for nearly a week and with that come panic attacks, usually more than one daily. it's getting to the point where I don't know if I can take it. distractions only make it better while they are there but worse in the long run and I've got a lot going on but to be completely honest. I have no idea what is causing me to feel like this. please give me some tips or advice on how to be happier and not feel like a piece of trash. Tia xx
