Boyfriends family

I’ve been with this guy for 2 years and I love him more than anything and I want to marry him and have a life with him but I’m not comfortable around his family. I have really bad anxiety and I’m usually okay around his mom and dad but I went to a dinner at his gmas house with the family and my anxiety was freaking me out so bad.. he made my plate for me and his gma told me to come get some food and I said “*boyfriends name* got me some” not rude or anything and it was like she scolded me was like “we serve ourselves here”. And it made me feel really bad about myself and I started to have an anxiety attack after she walked away and I was holding back tears. My boyfriend just held my hand and told me it was gonna be okay and I never told him what she said or anything I just told him it was anxiety. I don’t think his family likes me and idk what to do. Is it okay to still be with him if I’m not comfortable going to family events like this?

I’m 18 btw

Update

I went to the dr for it a few months ago and they prescribed me with 10mg citrolopram

And I my anxiety affects a lot of my everyday life like driving or going places by myself like the store, or talking to people I don’t know that well.
