I Suffer From Depression Anxiety Disorder

I have been having a really hard time with my anxiety lately, more than normal. I cant even leave the house without my husband . I went to pick my son up at work the other day . I was in my car with my son's dog . I go to his work all the time . There is cops there eating and its in a safe area . But yet I had a full blown anxiety attach . My chest started to feel heavy , I started crying , I couldn't breath . By the time my son go to the car I was a complete mess. Thankfully he is 18 and knows about my anxiety . He gave me some water and told me he will drive home . I went to my Dr. who changed my meds. However Walgreen is taking their sweet time to fill them . So I sit and suffer . I am ok when my husband is with me tho so there is that .
