Stressed

So my blood pressure has been ridiculous the last couple days. I've never had high blood pressure in my life until now. I went to the doctor last night but by the time I got there it was down... confirmed for me that its work-stress related. Today I was prepared to tell work that I could only work from home but when I sat down to log into the laptop I got the shakes and felt very anxious... i wrote in sick. I told them what was going on with my dad and how high my blood pressure has been. Also told them 'if' I work the rest of the week it will be from home. It took alot for me to lay it out like that but its done and no one has complained.  The next thing I have to do is even harder though. I asked for vacation so I could go visit my daughter in the dominican... I was flexible with dates when I made the request 2 weeks ago because there were still lots of inexpensive packages available for late feb. early march. Well it took them 2 weeks to decide and they said Feb. 26 I could go... now the package prices are up $500!! I want to ask again and see if they will let me switch to Mar 5th but I know my team lead is leaving at that time on maternity leave. But if I don't ask I will end up just buying a plane ticket, going alone cause SO can't afford $1600 and I'll have to stay with my daughter instead of on a resort which is only 10 minutes walk from her. I'm trying to think of a way to just work it into a conversation and comment how much more expensive it is that week but I'm waiting for someone else to start the convo. Also I have to answer to 6 people so I feel like I have to give my sob story to the world; it was hard enough to have to email in sick and cc 1/2 the office. I have to try to relax though or a vacation will be out of the question. I sure don't want to have a stroke or something. Life is just too much these days... I just want it all the stop
