How can one learn about their own anxiety and how to manage it but yet deal with someone else’s anxiety?

Backstory, I was diagnosed with anxiety a month ago and my pcp never gave me any coping techniques or any suggestions on how to manage this besides finding myself a therapist. Pcp also told me she doesn’t recommend I go on medication (I have had reactions to all my migraine meds) I have been getting really bad chest pains and waking up every two to three hours each night.

Well right now I’m in the process of moving (I live with my mom to help her out) and her anxieties have been through the roof and I feel like it’s all being taken out on me. Which in return flairs my anxiety lately. 

I messaged my therapist this question and I have to wait until Tuesday to figure it out..... she recommended i take breaks and cope with it...... 

On my own, I’ve tried counting back from 100 and deep breathing.....
