How should I feel?

I have a best friend who moved to Texas three years ago. We’ve been friends for 12 years since we were 18. Anyways she came into town last week, for 8 days. We had all of these plans and what not. She came over for dinner once and to see my new house, and that was the first day she was in town. After that I didn’t see her again until it was time for her to leave she came and said bye. Her reasoning was that her depression. Had taken a nosedive and she just wanted to lay in bed all day. I had no choice but the be understanding of that even though I thought it was shitty she was here for 8 whole days and I saw her twice. The second time barely even an hour.

Her 30th birthday was yesterday. One day after she got back to Texas. And she sends me snaps of her and her friends there going out for her birthday and having a good jolly time. I’m mad and I’m hurt.

Should I just... let it go? Or should I keep her at arms length for awhile. I’m married with a kid and honestly she’s my only friend that I actually see even though it’s only twice a year. So for her to come and we not even hang out, was hurtful. On the other hand I’m supposed to be understanding of her depression, which btw the reason is spiraled was because of a stupid decision she made. Anyways I don’t know if I need advice or just wanted to vent..
