Weird feelings

Hi im so depressed and found out I am pregnant and we are very happy for that because we want another baby. But today I am having so much on my mind thinking that I feel alone I don't have any friends where I lived neither family of my side who can help me out. I have three kids and I don't complain to have them. I love them so much but today I was trying to make an appointment for me because im very very itchy I don't why, if it is because a symptom of pregnancy. But then I realized how alone I am, is summer so my kids are with me all the time and my husband is working during the day I wanted to make the appointment but is so difficult, I don't want to imaging the others appointment that I will need to go. Well, my two kids start school in late august and my other child can stay with her grandma. For now I will have difficulty to go to confirm the pregnancy, physical and I know they do a scan at 12 weeks.. I want to tell everyone after 12 weeks and we are not ready to tell my hubby's family specially my MIL because she will tell her family. I had a miscarriage on March, we told her we were expecting and the next day his family start writing on Facebook about the pregnancy. In sorry I need to take it out, you girls are the only one im pregnant.. I can stop crying I hate this yesterday I was so angry. This is crazy! !!
