Tired or depressed?

[AnxietyForever]

I'm almost 10 weeks pregnant. I'm so tired! I have a 4 year old DS and feel like the worst mum ever, he's been watching tv non stop this week because I'm just so tired and DH has been working all week.
I've been snappy with him, house work isn't done, I can't be bothered going out and this is all making me feel depressed.
Will this pass?
I want to wake up full of energy but I'm just so tired

It's the tiredness I think. I get very snappy and a can't be arsed attitude when I'm tired. The tiredness in the first trimester and 3td trimester are the worst. It really messed me up until I was around 16 weeks!

For the first few weeks I was like that (maybe first 16 weeks or so). I am now in week 22 and it is SOO much better. Those first weeks I was lucky my DH could take over as pretty much all I did after returning home from work was lie on the sofa, and go to sleep between 7-8 pm! I am in awe of anyone who can take care of DC in the early parts of pregnancy, based on how I feel.
