Would you keep trying with this friendship?

We met about a year and a half ago. We had a ton in common, including the fact that we were both struggling to conceive.

I had a miscarriage about two weeks before she got her BFP. I was super happy for her, let her rant about how uncomfortable it was, etc. We didn't see each other too often because we're both homebodies, but we chatted often.

I didn't go to her baby shower because as happy as I was, I just couldn't bring myself to go. I had spent the whole morning crying and I just couldn't. I told her and she understood.

She had her baby, and I went through a horrible depressive stage. Not related to the baby, but just in general. I've been struggling with depression since I was a teen, and I didn't speak to anyone if I could help it for a month. I didn't even spend Christmas with anyone. She said she understood, as she herself struggles.

I know people always want to be around people and their babies and that's overwhelming, I typically go see babies for the first time when they're a month or so old. When the parents have gotten into a routine and they're not inundated with visitors.

Anyway, I came around and I was finally going to meet her baby but then there was a medical issue. We chatted almost daily when she had this issue. Then immediately after the medical issue, we went into lockdown.

Anyway, our conversations have become far and few between lately and I know she's busy with a young baby. I'll send her a meme or a message every couple of weeks, she'll read it and not really say anything, then she'll message me about the blue again and ask how I am but not reply back.

I'm just wondering at this stage if it's even worth keeping the friendship. I really like her and it's unfortunate that I've not been able to meet her baby yet (she's now 7 months) and I feel maybe that's why she's not talking to me so much? Or maybe now that she's had a baby she feels we have less in common? Or maybe she's just busy and can't keep up a friendship (which I totally understand, I've apologized many times for bad communication my side. I'm really bad at talking to people, and I am extremely busy with work and home responsibilities). I dunno.
