potential mirena complications?

Sevy

okay so I have the Mirena, I got it placed in April of 2017. Originally I got it to slow my periods down because they were extremely heavy and painful. the birth control part was just a plus. and over time I have definitely noticed a change in my cycles. i cramp really hard just before it happens, like a pain that makes you nauseous, and that's how i know my period is about to start. they last longer but I bleed a lot less, I hardly cover half the tampon, BUT it lasts for 8 days, 10 max. and during this time I'm extremely depressed. I get very emotional and then very irritable back and forth very easily. it's easy to set me off but I don't know if I'll cry or snap. I notice a significant drop in my ability to handle things and I get suicidal thoughts easily. everything gets very overwhelming and sad. It's like I'm on the verge of tears every second of every day. it's so intense and I often cry heavily for long periods of time, and I don't trust myself being alone as I have a history of severe depression/self harm. the thing is, I only feel this way when I'm on my period, when I stop I feel absolutely fantastic and life is amazing. when I menstruate it's like my world comes crashing down for no apparent reason at all. I can't remember if it's always been this way because I just remember being really depressed consistently. I'm sorry if this wasn't explained well, I'm just tired of feeling awful when I'm on my period and I'm concerned that I'm intolerant to the progesterone. I need advice and opinions, anything helps.
