<human>: Umm this might not be the right place for this but I'm not really sure where is. 
Some background: I've been told by a doctor and a specialist I have chronic fatigue syndrome.  I've been seeing said specialist for about a year now but they think it started years ago and got gradually worse.  Well since before xmas I've been having dizzy spells,  this had lead to fainting a few times. I thought I was fine.  Nothing to worry about. This happened a lot when I was younger.  I even turned down the anti depressants and anti anxiety medication the specialist was going to prescribe.  

My boyfriend left to go visit his family this morning,  and I haven't stopped freaking out since.  I'm shaking and dizzy and crying and I can't stop, I calm down a bit when I focus on my breathing but then it gets bad again.  

I didn't tell him about fainting a couple of times before and he said that I'd betrayed him by not telling him.  I phoned him at the time but he was happy (for once,  he's also quite depressed) and with an old friend of his. So I didn't say anything because I'm not that girlfriend. 

Well I've been freaking out most of the day since he left and I managed somehow to pass out during my freaking out, I was sitting down at the time,  so I'm scared it's getting worse.  I've been concentrating on my breathing to calm myself down a bit but I keep getting worked up again. 

What do I do?  He only just got there and only gets to see them occasionally. He can't do anything anyway as he's in another country right now.  So can I just not tell him, make it to the morning and go and see my gp? Or are there any better ideas?

Can you provide a brief overview of the text?
<bot>: do I tell my boyfriend who thinks it's a betrayal that I didn't tell him before,  that I passed out again or can I get away with not telling him?
