Feeling really down

So I'm 16 weeks 5 days preggo with my 2nd babe and I've struggled with anxiety and depression off and on since I was a preteen. I had a rough childhood. When I met my now husband I was in a really good place and hadn't been depressed for a long time and then I got hit with severe post partum depression with my son. It was my lowest low and I didn't want to tell anyone because I didn't want to seem weak. It went on for close to a year and I hadn't been depressed for a little while but this last couple months has been rough. It's terribly cold where I live and I've been staying home as much as possible to prevent getting myself or my toddler sick plus my car can't get around in the ice and snow. It's just really depressing being home a lot and being broke not able to do much at all. I've had a really tough day today and my husband was snowed out of work today and he has no sympathy for me when I get depressed he's like I hate when you get like this just be happy for what you have and I'm like ok let me just snap my fingers and change my feelings... it dosent work that way. I'm very grateful for what I have and I know we are blessed to be where we are. But I can't control my mental state sometimes and having all these pregnancy hormones don't help. My birthday is in 2 days and my husband keeps reminding me of it but it's honestly depressing because we can't afford to do anything and if I get any birthday money it's gonna have to be used for nescities until we have the money for me to spend it how I want. I know I sound selfish but it sucks. My birthday has never been a good time for me. This pregnancy has been so hard. I've been so sick and exhausted trying to take care of our son and keep up with house work.. I feel like I'm stretched too thin and my husband dosent seem to have much compassion for me this time around. I love him to death but he can be an ass sometimes.
