Am I being unreasonable?

Sorry for posting this here but I’m overthinking everything and just wanted some advice (or someone to tell me if I’m being a bit of a b*tch) I’m a stay at home mum and my husband is in the military, he’s always really busy and works hard and works late so we don’t see him much - mainly on weekends if he’s home. I’m struggling really bad with my mental health (horrific anxiety and feeling quite low) on top of making sure the house is running, pets are looked after and our 1 year old is happy… it’s honestly exhausting. I have 0 time to myself, no family to help, it just feels like Groundhog Day everyday (grateful for my life, but struggling) Anyway, my husband’s work do a lot of events that he attends and they also run these activity packages where they go abroad with work for 1-2 weeks to have fun… doing stuff like mountain climbing, kayaking and drinking. It’s basically a lads holiday. He mentioned it to me the other day how they’re running one in a few months and I reacted badly to it and I know I did. I said I’d struggle with it as my cup is empty, I don’t get breaks from being at home and being a mum, I don’t have family here to help, I have no friends nearby as we move everywhere due to his job… I have no career myself at the moment and it would suck sitting at home watching him go on holiday having fun. He works hard and I feel horrible for even going moody about it but I just find it really shit how he’s able to leave the house and not think about being a dad for a bit, I can’t do that as my daughter needs me and I don’t have the opportunity to leave the house whenever I want. He attends a lot of things with work but stuff like that just makes me feel a bit rubbish. We don’t do much as a family and I barely see him now due to his working hours so it just always feels like I’m the one at home keeping everything running whilst he’s out living his life. It honestly sucks. I just feel like I’m sat on the sidelines watching him succeed in his career and have fun and I’m here barely surviving the day. I tried to explain to him how he doesn’t know how it feels, he gets to leave the house - granted it’s for work - but he gets that separation to socialise and have a break from the house… he comes home with fresh eyes and mind. If there’s events going on at work he can just leave the house and attend them, no issue. He’s been on these holiday packages before… he hasn’t since we’ve had our daughter but I just can’t help but feel resentment? If he went it would make me so upset and I know I’m awful for even saying this as he deserves to be happy too and to live his life. I don’t know why I posted this on here. I feel really lonely at the moment and guilty that I caused an argument. I’m just really struggling.
