Stunning visuals here! Love the story told here. I love the description of darkness veiled within the metaphor.

I think you are saying that although it is technically spring time now, nothing feels like it is blooming anymore and i read it two ways here. It could be taken at face value in which the world has gone mad and it doesn't feel like spring but i think the hidden meaning (because of the ending) is

that you feel nothing is blooming inside of you anymore. You are veiled in the memories of summer and the past had happiness. A lot of people equate summer with bliss (and i think you've done so here ) but

The present is winter time and you feel saddened because of the winter you feel inside of yourself and despite your best efforts nothing blooms and all feels empty.

I also believe all the places you mentioned are places with good memories (creeks, beaches, etc) that you don't enjoy or enjoy less now
