Feeling depressed

Ok so my husband and I have been married for 2 years, i am 12 weeks pregnant with our first bany, and for the past couple of weeks i think i've cried pretty much every day. i feel really anxious and depressed. I probably should be able to talk to my husband but i knew he wouldn't understand. Before I got pregnant we had a great relationship, but I feel like now he's getting sick of me, he gets in from work and just plays on the computer until stupid o'clock, acts like talking to me is a huge effort. tonight i kept crying in bed so i got up and went downstairs, he woke up and came down, gave me a quick hug, i told him i've been feeling really down and it was obvious i'd been crying a lot, but he just said to come back to bed and get some sleep. i know what he's like and if he cared i thought he'd at least be a little bit concerned, but apparently not. just feel alone and unhappy 😔
