Struggling single mom. Hurt by the distance of my family. I am probably expecting too much.

I’ve been trying to get over this in therapy and work on my feelings of resentment, which I’m not sure if they are valid or not. As the eldest sibling in the family dynamic, I was heavily parentified and made responsible for my younger siblings very often since around the age of 11. I also emotionally supported my father through his divorce and as a young teenager with her own apartment would always help my siblings by letting them stay with me when needed etc. Now as an adult, I nurtured a close relationship with my sisters child, often spending weekends with her and taking her to the beach or the mall. I really love my niece and am very grateful to have a close relationship with her now that she is a young adult. I fell into an abusive relationship 10 years ago and had to flee with my newborn child. I went back to my hometown hoping for emotional support from my family. Also, I hoped to provide an extended family to my daughter so I could raise her within a loving village rather than alone as a single parent. She is now almost 10. For the most part we are very alone. I have struggled with my mental health and with managing work, childcare and self care . It has been extremely difficult but I am so happy to have my child. I’m happy she is free from an abusive home life. However, on lonely weekends like this one, my mood plummets knowing that I have family in the same city - a mother, a father and a sister and that nobody reaches out or shows interest in how we are coping and no one wants to be a part of my daughters life. My mom will visit as long as I am present , which makes me sad too. It’s like she doesn’t want to have one-on-one time with my daughter and get to know her as a person. When I feel resentment, I also feel guilt and that I am expecting too much. I feel like my youth was sacrificed to care for others including my siblings and my father. When I feel this way, I want to disappear. I want to cease all communication with family and just find a way to move forward without them. It feels like it wouldn’t be much different anyway. I am alone with my daughter always. I understand I can’t expect help nor should I expect family to be around. Any advise on how to cope with this would be very appreciated.
