Kindergarten :(

Tina
My daughter started Kindergarten on Monday and I've been crying almost non stop. ( never in front of her). She is my only biological child. I raised her alone until i met my husband when she was two. She's now 5, super smart and is doing great in school but now im depressed. I just feel like i didnt utilize our time together well enough and now i barely get to see her. My husband just thinks im acting dumb and has been no help to my emotions whatsoever. I honestly dont think he knows how. But seriously tell me im not the only parent who goes through this and that it will pass :(.
