Pregnant and alone and so stressed!

Things have been crazy stressful lately. Im a full time working mother of two with another one on the way. Im a little over 4 months along and I am currently doing it all myself. About a month ago, my husband was arrested for a domestic issue with me (long story short, I had to call the police as he was a little too angry and scary) and the police took him away to jail that night. He is currently under a no contact order and the district attorney told me that it is very unlikely the order will be lifted, at least not for a while depending on his decision on completing anger and parenting classes. Anyway, his charges were reduced to unlawful touch which is a misdemeanor but the no contact order remains. I am trying so hard not to feel depressed or overwhelmed with life lately and trying to just get through each day and be strong for my children. But some days I feel so down and stressed and I dont really have a support system to talk to about any of this. My husband's family treats me like I have the plague or something for doing this to their poor son. I dont have the heart to tell my parents about this situation, they have enough going on in their lives to worry about...the last thing they need is more bad news. Friends of mine all have their own lives and their own families to worry about so talking to them about my problems seems burdensome. Im busy as heck just keeping up with working 10 hours a day and my two current children. The weekends are dedicated to catching up housework and preparing for the following week. I have absolutely no time for myself and no time to rest. And with my maternity leave coming up, I need to save up my leave as much as possible since I dont know how long I will have to depend on my income only for me and the kids and the baby. I really need an outlet, I think I mostly just need a hug, reassurance that everything will be ok, someone to take care of me for once and to cry and vent. Most days Im ok and thankful that I have so much to keep me busy and my mind off of the situation with my husband. Other days, like today, I feel so depressed and desperate to have my husband back (the nice version of him) to help me and be there for us. Going to the prenatal appointments by myself can be a really sad experience for me. I dont even feel pregnant sometimes because I dont have anyone to talk to about the everyday little things. I know Im a good mom and will always do what I have to do for my children, but I worry about being so alone.
