All about timing

I have been living in chaos for months and months, which came to a head recently. It brought me to a place where I questioned my friendships, my drinking and what support I need. I started Therapy, cut back on my drinking and developed new friendships that are filling a need that has been neglected for far too long. Last night my birth mother passed away. We did not have a relationship, I barely knew her and I made no effort to try but neither did she. I went for a park date with a very good and very insightful friend this afternoon. She tells me that life is strange in the sense that I have recently built up this amazing support network and I can lean on it as much as I need to. She also says that if this was 6 months ago, pre-amazing support, I wasn't in therapy, I would have just gotten drunk and stayed drunk for 6 weeks and wouldn't shed a tear.
I am in a place that crying is abundant, more than I have ever done. I don't want to drink while I am sad because I need to feel everything right now. I have a therapist that I can call anytime if I need to. I also have a group of wonderful people that all made an effort to see me even just for a hug.
I am angry because I was going to start talking about the roots of some of my issues in Therapy and now they are gone. I think this is extremely unfair and I am pissed off.
