No family Members at the wedding

Hello ,I've just read a few threads about bride's family can't come to their wedding it's heartbreaking.I want to advise on how would I survive my wedding this October.Just a brief background. Me and fiance decided we'll have 2 weddings one in my country then 2nd on his. Since both of our familes can't travel because its expensive and medical reasons.We had the first last June on my side it was amazing day everyone is happy.I came from a close knit family.I'm both close to my parents and siblings.When were home my whole family accepted him warmly and they made sure that he wont feel alone the whole time he was staying with us. October is fast approaching the 2nd wedding is about to happen and I'm already having mixed feelings about it. Unlike other brides my husband's Immediate family (mom and sisters) are not warm to me at all.To them I will always be an outsider. The thought of walking down the aisle alone is making me cry already and knowing that the new family i have doesnt like is just heartbreaking at the same awkward.I would really appreciate your advise on this matter.

Thank you for taking time to read
