6 month anniversary of miscarriage

I'm 14 and 6 months ago today I had a miscarriage. My boyfriend doesn't share the same pain as I do because I guess guys move on faster or he doesn't want to appear weak? I have no clue but I feel like screaming and crying and letting people know I am in pain but I cant. My mother wouldn't let me tell anyone else other than my boyfriend and her so no one can even know I am not okay right now. I feel so hurt and even though I am homeschooled I cannot just stay in bed all day like I want. I have 3 small siblings, 2 almost 2 year olds and a 3 month old I must take care of while my mother is at work. I have no choice and it breaks my heart every day. I have been diagnosed with PCOS and I am so scared to get pregnant again because I cannot go through that kind of pain again. So a week from now I have my appointment to get another shot of my birth control...but I'm switching to the copper IUD ParaGard. Is anyone else going through this pain?? Has anyone else gotten this IUD?? Any advice??
