Is sharing your struggles considered a lack of gratitude?

Assalamu alaikum. I'm a mother of two. Today I was so drained that I ended up sending a tearful message to my husband, saying I'm utterly exhausted and feel like I want to escape for a bit. For some background, I have a very active toddler and my 8-month-old has been ill for four days now. I haven't slept well for about a week-rest has really been declining since my little one was born-and I'm barely managing. I just want to get away from it all for a moment. Does this mean I don't love my kids? Absolutely not... I love them dearly. Earlier, I shouted at my toddler because she wasn't sleeping and I was so drowsy. I ended up moving them both to the bed, and all three of us were just crying together. I honestly don't know how to handle this. So in the middle of all this, I messaged my husband, sobbing about how worn out I am and how they're making me feel so annoyed. Am I being ungrateful by saying these things? I'm not sure where this fear comes from, but I learned that venting about your problems might make you seem ungrateful and unhappy with your life. It made me think that Allah is giving me a relatively easy test, and if I'm struggling after just a week of sickness, maybe I shouldn't complain at all. I also worry that being ungrateful has consequences-that Allah might take away my blessings. I'm scared... what should I do?
