Reaching out to an old friend, who you haven't spoken to in close to a year?

We haven't texted since Jan and it's coming up on a year since we've actually spoken. This friendship goes back decades to when we were little girls.

**Sorry that this is long, but I would really appreciate any advice or shared experiences.**

Backstory: I went into a bad depression and completely distanced myself. I stopped doing things that I loved. I am doing better now. I still go through the motions, but there has been improvement. I'm still learning to cope. Back in Jan, we were supposed to catch up on the phone and I stood her up. I just couldn't get myself on the phone. I couldn't even motivate myself to get out of bed or take a shower or even brush my teeth. That's how bad things were. I've always struggled with anxiety, but depression was completely new to me.

My feelings are complex on the matter. On one hand, she knew I was going through mental health issues. NGL, I'm a little disappointed that she has never bothered to reach out or check on me after all of these months. My bitterness stems from spending countless of hours listening to her talk about her therapy sessions, her struggles and talking her through it. However, an even bigger part of me can't blame her as I ghosted her. Mental illness or not, you don't bail on your friends. And I'm disappointed that I let myself spiral.

I want to reach out because I genuinely care about her. Even if she can no longer accept the friendship and tells me to go to hell, I would still like to at least apologize.

My questions for you are:

1) A new friend from group therapy suggested that I first send a "hey, how are you?" text to get a gauge, but I kind of just want to send the full text instead of beating around the bush. (Btw, I am texting instead of calling because she hates talking on the phone as she has 2 roommates in a small apartment. Not a lot of privacy. She has always preferred messaging.)

2) How would you feel if you were in her position and an old friend who left just randomly reached out after such a long time? What would you want to hear?

Thank you for any advice you may have to offer.
