AITA for wanting a hug from my mom?

I (14f) am on summer break, I graduated middle school this year and therefore I won’t be seeing my friends next school year. As a result of this, I am always very lonely (I could reach out online but I’m scared). Today I was really sad, I was at home all day and downstairs by myself. My dog was being terrible and I was overwhelmed. I texted my mom for help and she didn’t answer. I eventually started crying and went to my parents’ room. I said I was sad and overwhelmed and hungry and my mom said something about her fever and how she couldn’t help me (it was hard to hear over my crying also I’m very aware this is an overreaction). I started crying harder because I just wanted a hug and I asked her and she said no. I was upset the whole day because I was convinced she didn’t like me anymore. It’s been hours since then, but I feel guilty for being too demanding and sensitive. She’s said that she does love me and it’s fine because she was just tired. But I feel guilty and ashamed. Was I an asshole, and how do I get rid of my guilt?
