Do bad things happen in threes??????

So I have been trying very hard to stay optimistic about life and all my challenges. I know people have it worse than I do so I should thank my lucky starts but things have been happening and I feel like throwing in the towel. I have been having some medical issues and spending way more money than I have to get everything taken care of. The last few days have been physically and enotionally painful. Then I get a call from the health and welfare saying my son doesnt have health insurance because his dad is supposed to carry Caleb for the insurance. Well, Caleb is a sick kid having him on Medicaid is the best thing because I cant afford to pay the insurance. If it is in Calebs dads hands to give me money for insurance every month he wont do it. Then Im really screwed. Especially since I cant work this summer and Im having to live off my tax money. His dad is also supposed to pay 62% of daycare and has never paid a dime!!!!!! Im freaking out! So now my three year old has no medical insurance and I cant put him on my insurance because im quiting for the summer PACE program. I think my best bet is to take Caleb's dad to court and sue him for daycare and medical expenses. I dont want to have to do that because I will end up looking like the bad guy like I always do. Then I find out that I have been giving my brother rent money to help him pay the mortgage and he is already two month behind! So if he doesnt get caught up on the payments, Caleb amnd I will be looking for another place. I cant handle all this! I feel like Im alone against this crazy world.
