Anxiety and Depression During pregnancy

I will be speaking to the head of high risk clinic tomorrow but I just want insight. Ever since the ending of last week I have had sudden bouts of anxiety. Im 7 weeks now and God willing everything is okay. I can't sleep unless if I take half of a benadryl. I have pregnancy rhinitis so it does help me breathe at night. I just get so stressed out and irritated, that my body responds by vomitting. I also end up crying. I hate feeling this way because when im good I can do stuff around the house. When I'm bad I feel like I can't even look at anything (tv or read) or do anything or else I get nervous and my heart races. I don't end up with a panic attack but I feel like its building up to that point. I am desperate for relief as with my son I was on zoloft because the same thing happened but later on in my pregnancy. I feel like this pregnancy the baby hates me. I havent even been able to be excited. I feel guilty.
