Depressed what is life

I’m 10 weeks pregnant with my 3rd I have a 7 and 2 year old

I can’t stop crying over the last two days I feel so low and everything is bothering me

I can’t sleep I can’t eat and even looking round at my house work is making me more low as I have no energy is clean but not to my standard I feel like a bad mum because I’m so moody. My two year old don’t sleep he wakes up at 7am and stays awake all day at nursery and don’t go to bed till at least 10pm then wakes up screaming in the night at least twices he’s so hyper he won’t nap during the day things r getting to me my oh works away

Sorry needed to let things out currently crying and feel worthless

EDIT

I moved away from the town I lived in and all that is here is like two friends I met from taking my son to school and my MIL but she is no help as she is always ill I say ill in a funny way ( theres nothing wrong with her)

I just hope it’s my hormones I just feel under a lot of stress I lost my job because they was letting people go and now I’m a SAHM it’s over whelming I love my kids with all my heart I feel like I do everything for everyone and no one gives back my OH has ADHD so I basically care for him to. Thanks anyways I’ll be fine tomorrow just one of them days I’ll put my smile back on and pull myself together my baby’s r the reason I get though life 😍
