help please

So much has happened between my partner and i, we have been together a little over 2 years, since july 2019 we have had 3 late abortions. I have so much guilt but also have lost all confidence and i am so insecure with the way my body now looks, i’m struggling a lot with it and i can’t even bare my partner touching me incase i disgust him, i’ve tried to explain this to him but he just doesn’t understand and i don’t know what i can do to stop feeling so down
