Conflicted Feelings

I am writing this at 23:20pm.
 I suppose the easiest way to start this is to come out and say what is wrong with me... Tonight I overheard my mother and father talking in the living room when I was in the kitchen preparing things for cleaning the bathroom, and part of their conversation was going through a dilemma we had the previous evening with my sister.
 She had thought her daughter had dropped one of her toys somewhere on the path on the walk home and asked my father to go out and look, and to cut THAT story short, it turns out it was found in the bin at her home and my father had had to go out twice and his hand had gone numb from the cold and poor circulation.
 That unfortunately wasn't the only thing wrong with him; he has had a condition with his heart for a long while now which was brought on from a very small heart attack some months back which I had to probe my mother for information on, because they know I don't like it when information is hidden from me. My father now takes his medication when he needs it, as it helps to bring down his blood pressure and calm him. It turns out from the conversation I overheard, he had another of these "warning attacks" last night.
 Even as I write this I'm not sure if I should cry or not, because I know they are doing this so I don't worry too much, but at the same time I want to, AND need to know that my own father is OK, because if he isn't then unfortunately I have to plan for in case the worst happens such as finding extra support for myself and my mother, finding some form of benefits so we can afford to live in this house and live in general, and a lot of other stuff such as if I will be able to continue my education, how will I afford transport to and from Runcorn to do major shopping runs, how will my mother cope and will we both need some form of counselling... it's not nice stuff I wish to think on, and right now I am scared I may lose my father.
 He said to my mother tonight whilst I was in the kitchen that he thought it was because of how stressed he became around my sister, and the stress got too much; it makes me wonder what else they're hiding from me.
 The reason this is entitled conflicted feelings is because I am also excited for going to Chester tomorrow to meet Blake, and start our wonderful day. We have a lot planned, and I will be shocked if we can fit it all in one day, but I am excited to meet the man I have new-found feelings for.
 He treats me like a Goddess already, and with what we have planned, is already treating me to a lot which I will feel grateful for in some way, but also I will feel so cheeky that things are being paid for me, I suppose I'm just not used to it. It has been a long while since someone has done things like this for me, or should I say in this case will do.
 So on top of being excited, I am also upset/worried/nervous, whatever you wish to call it really. It's taking me longer than I thought to get this all down, but I am talking to my friend about this situation now with my father, and I'm starting to cry a little now. I suppose it's what I need, but it hurts.
 I have stopped writing this at 23:44pm.
