I feel like a huge part of my identity is lost after 1,5 year NC

I went NC with bpd-mom 1,5 year ago and partly I feel great, I have more inner harmony and no drama. But the thing is, I grew up with my moms side of the family and we spent alot of time with aunts, cousins, grandparents and had alot of birthdayparties and "get together" etc. But now when I'm NC I can't attend any of them. No events or birthdayparties because she's there. I have lost so much contact with other relatives that I get along with and miss so much. I just feel so...lost... Any advice?
