Pregnancy Hormones are distroying us

This week as been a terrible week, I honastly feel like i could run away and never come back. We are 8 weeks and 5 days pregnant. We have lost 2 dogs this week and one has been very unwell. All we do it fight i have been unable to hold back how i feel. My other halfs negative attitude has made me literally scream at him and im never like that, i sat under the shower crying that i hated how i feel and how i cannot continue feeling this way. For years i battled manic depression and last year after intensive counciling and will power i managed to get myself of all my medication and was finally happy. This is making me feel like im right back were i started and when i confronted my other half he just says well you don't ask and im like but you just expect. Anyway it's so long i dont want to get into it. But please tell me these feeling stop or calm down because i really feel like im drowning atm
