Depressed and anxiety

I'm 15 weeks pregnant and I'm very depressed. I don't know how to cope with it. I also have anxiety. I was diagnosed with both at a very young age. And my husband just don't seem to try and help me. He works everyday and we hardly see each other and when we do he is very rude and mean to me. I have very bad pregnancy mood swings.. And he don't understand at all.. I feel like going crazy. I use to be heavy smoker. I quit since I found I was pregnant but he still smokes and he knows that it is hard for me I crave them. But he still continues to smoke. We got in a fight and he left I don't know where.. I feel so much anxiety i think I'm going to have anxiety attacks.. I feel like this pregnancy isn't important to him at all.. I don't know what to do.. But cry 😥😥😥
