How to i protect myself and my son?

Family drama

I get alot of anxiety when it comes to my mother and two sister. I feel like im the ugly duckling in the family. My mother has never told me she loves me in person. Only ever by text message. My sisters claim to not see it but it gets to me every time. When i was about 13 me and my mother didnt have the best of relationships, i was kicked out of home and we have since rekindled our relationship. I still feel like she holds resentment towards me. When its a special time for me like birthdays or anything like that its not important. Usually my family picks a fight and i end up spending these dates alone. I have an 8 month old son who has a cousin the same age. And there always boasting about how well the cousins doing in his development and always buying the cousin things and not my son.how is this fair? How will this make my son feel loved? I feel like the resentment they hold for me has been passed onto my son. I never ask them to baby sit due to this. My mother in law canr say enough how proud she is of the mother i have become and how much she loves me. Why cant my mum? I look at how i was raised and know that i will do everything in my power to raise him better and show him he is loved every day. I promise myself that he will never know the feeling that i feel. How i can i protect him from feeling that when it comes to my family? How can i get through this myself and still have a relationship with them?
