I’m fat!

I never been skinny really! & it never really bothered me. So idk why now i feel so big, I dont like what i see in the mirror. My husband tells me im beautiful but what else is he suppose to say? Hes my husband! Don’t like how clothes fit on me, don’t like how i unlike myself. Its gotten so bad that every time my husband and I have sex i feel so embarrassed of my body, try to cover up which makes my husband mad. I need advice! Plzzz... BTW im going 23 years old and weigh about 220. Have never had kids!
