I am not yet of age and my parents are divorced.

My mom is a single working parent and provides alone. I mainly live with her and our 2 lovely cats. 

I go to my dads house when i have a long break. He is in a long-term relationship with a woman i consider family. Both of them work full-time and live in a house. 

When I visit my dad they give me alot of gifts. Varying from candy to watches. This time I went there I received a new watch because my last was broken. I also got a new phone because my b-day is in a couple of weeks. And I know my mom wouldn't be able to afford it.

I feel so much anxiety because i'm worried she would feel bad for not being able to give me gifts like that.

What can I do to not feel like this?
