Feeling Low

Hi all, not really sure what I’m looking for mostly just to get the way I’m feeling off my chest. I’m about 5wks pregnant with my second child. I started a new job last week and my husband has been working away since September. I’m really struggling with my mood, I feel really teary and low a a lot of the time and because of new job and no hubby about I feel very lonely. I have my two year old keeping me busy but I’m shattered and emotionally drained, finding it hard to get motivated to get up and go to work and after I’ve put my toddler to bed I usually go straight after. Not really sure what to do or how to handle my emotions at the moment or how to regain some energy.
