I have anxiety and it's been been a bit worse lately because I'm worried for my best friend.

In the course of a year, she's lost her job (Covid), her cat is slowly dying, went through surgery for spinal hernia, car she just paid off is starting to have issues and her boyfriend is an a-hole.  So she's spiraled into depression.  I send a text almost every day; memes for laughs, "hey how you doing", video game news, offers to cook for her (I love cooking/baking for loved ones), just stuff to let her know I'm here for her. Maybe she responds, maybe she doesn't.  I found out I'm one of the very few she stays in contact with as everyone else wonders if she dropped off the face of the earth.  If she's not applying to jobs, she sleeps.  Dropped all her hobbies and interests just to sleep.  Rarely eats unless a-hole bf screams at her for not taking care of herself.  Doesn't leave house unless it's for bare essentials. 

I worry about her.  I mean, she's like a sister to me as we've been best friends since we were little kids.  But it's not like I can drag her to a doctor (her state health insurance hasn't kicked in yet) or chase away the dark clouds in her head.  I wish I could do more for her.  I've been where she was and I hate to see her experience that pain.  Every day I find myself anxious for her well-being, hoping she doesn't sink any further into despair.  

Is there more I can do for her?  Am I even doing enough?
