Issues and having problems

Michelle
Been having issues and I'm feeling that ever since I found out that I'm pregnant my bf hasn't been supportive and we have a four year old that I have to chase and doesn't care I'm consider high risk and lately been even more tired and somewhat dizzy I didn't have any symptoms until I was three months along and now it seems that I have nobody to talk to and alone and now thoughts bout giving up the baby and loose everything I care about
