Context: 21, student, from a poor, single parent family (mum).

Been struggling recently, no social life, feeling disconnected, working and studying full time. Decided to confide in mum, but called her out and told her shes never home or there for me (which is true). Noticed that she's more anxious now, almost like she feels less safe around me. Should I just tell her nothing from here on out and let her be with whatever she does? What can I do to deal with problems on my own?
