My mom wants to get me a service dog for severe anxiety

I’m currently 15 and struggling with severe anxiety. I have dealt with anxiety my whole life and had it diagnosed at 12. Im on anxiety meds but I can’t find one that genuinely works on me. My anxiety keeps me up and night and makes me so physically ill I cant attend school.

Over the past few weeks it’s escalated to the point I can barely go outside and my twitching is back and horrible. I’m exhausted mentally and physically from this. My heart is constantly pounding from my anxiety and it makes my head pound.

my mom wants to get me a service animal for this so I can go outside and have a tool for my anxiety since there’s not many that work. I’m embarrassed and it makes me feel entitled for her even considering it. I feel like I’m taking away services from people in need. I’ve tried breathing, company, essas, music, etc. It’s getting worse and I can’t have my mom in a different room when I’m public without me being atleast in tears. it’s not a clinging way but I get so scared alone in public and it gets worse every da.

she says the animal would also be for other stuff like my depression, mania, and my overall mental state. I just feel so anxious towards looking entitled for having a service animal and getting judged.
