Anyone else feeling overwhelmed?

I am almost 32 weeks with baby #3 and I feel like my anxiety has worsened the further along I get. I’ve had anxiety before, but never been to the doctor about it because it wasn’t “that bad”. Lately I’ve just felt so overwhelmed with everything. Life and just everything that comes with it. I love my life don’t get me wrong and I wouldn’t trade it for anything. My husband works so I can be a stay at home mom and I really do love that he works so hard for our family. I haven’t worked in about 5 years and before that, I worked just about every day. I am not the best housekeeper but the house still gets picked up and a good clean once a week. I pick the kids up from school and take them to their appointments and extra activity stuff. Lately , they have not been listening at all. I have to start yelling for anything to get done. Whether it be to stop fighting or to clean up their toys to even brushing their teeth or going to bed. I. Am. Tired. Between getting things done at home and the kids, I am emotionally exhausted. And being pregnant on top of that , I am physically tired. All. The. Time. I have zero energy to do anything. And I worry all the time that my husband resents me for it. He doesn’t ever flat out say it, but he will make comments here and there. Like sure wish my clothes were put up and I don’t have to search for everything. We have been together for 12 years (we are high school sweethearts) and I just worry that one day , he just won’t be able to take it anymore and leave me. I’ve voiced my worries to him before and of course he reassured me and says he will never leave me because he can’t live without me. But the worried me can’t help but think the worst constantly. I recently told my husband about how I d been feeling lately. That I have been so overwhelmed by everything and he was like by what ? All shocked. I explained it all to him and told him that I think it may be time to talk to my doctor about my anxiety and he said he doesn’t think it’s anxiety and then left the conversation at that. It’s like when I talk to him about any of my personal issues like this, he just brushes it off like I am just over reacting because I’m hormonal and pregnant. And so that jus make some keep everything inside even more and it’s getting to the point where I can’t keep it inside anymore. Housework is stressing me out because I know it needs to be done, but I just don’t have the energy to do it. At all. My kids stress me out with their constant fighting and not listening and attitudes and what not. Typical kid stuff. And I know it’s not all them, it’s me. I’m just so tired. I don’t know what else to do.
