What is wrong with me!😭

Okay so I'm 33 almost 34 weeks pregnant and I have absolutely NO motivation to do anything😔 i know with being pregnant comes tiredness and maybe even a little bit of laziness but this is completely different because I actually don't feel tired at all I just have no motivation and its not that I don't want to do things I just can't get myself to do them I stay home all day everyday while my boyfriend goes to work and I feel terrible because he comes home from work and all I've done all day is lay in bed when the house is a disaster and dishes need to be done ect. I feel so bad because there is hundreds of things in the house that could be done (make dinner, dishes, laundry and basic clean up) I want to do these thing so bad but just can't bring myself to do them, I'm not sure if I'm depressed? Even thought I don't feel particularly sad I'm actually quite excited about becoming a mom to my son (he's due nov. 27th) before I got pregnant I was on Zoloft for 2 years and I believe it helped me tremendously to function like a normal human being (I have terrible social anxiety which is why I was put on the Zoloft) my doctor said I could take a low dose of Zoloft but I'm not willing to take the risks that come along with that kind of medication while pregnant I will be going back on it as soon as I can but until then i just don't know what to do with my self 😭 are there any other mommies out there that have delt with this type of thing? I feel like such a terrible person like I'm not good for anything except laying in bed all day and I worry my boyfriend is going to get fed up because I literally do nothing I don't want to be like that but I just feel like I'm in a slump 😔💔
