My friends didn't tell me about B.O

Hi
Im a 20 year old girl. Im happy, pretty out going but can be shy sometimes. I have a great boyfriend and a big group of friends some of which are closer, older friends from school. On a recent night out with my closer friends, we were all on a mini bus on our way to a club. I was sat behind two of my friends and overheard them talking about how I have a problem with b.o and every knows and talks about it but they cant bring themselves to tell me. It was the most horrible horrible thing to overhear in my life. I couldn't believe it, I had no idea I had a problem let alone my closest friends knew and talk about it.

I confronted my closest friend and told her what I overheard. Basically it has come out that I have a problem with b.o and that my friends and people I'm not even that close to have talked about it to my closest friends. Apparently its been going on for years aswell. I talked to all my closer friends and some people say it wasn't a big problem just on the occasional night out and it never crossed their minds to tell me while others won't tell me what has been said but say people are lying to me.

I'm not going to let this get me down though, so I have a problem with b.o? I can get rid of it. People will have to accept me as I am there is more to me than b.o! There are plenty of much worse things in life. My boyfriend has been amazing through this all so supportive which I am so grateful for. The only problem is Im so angry with my closest friends! I feel embarrassed and mortified. The whole thing has been turned into a big drama with people passing blame around for not telling me when all it would have taken was a quick chat. I don't know how bad the problem is because no-one will tell me the truth I cant begin to explain how hurt I am this could have been solved years ago now I get nervous when I'm out and think people are talking about me or feeling sorry for me.

I find myself beginning to go out more with friends who don't know about the problem or at least haven't spoken to me about it. I feel bad as I don't want to penalise my friends for eventually telling me this. We have all been friends to some degree since comprehensive and while we don't always see eye to eye we all meet up and talk regularly. So I don't really want to loose that, there has to be something there for us to have been friends for so long right? It's just how can I trust them again? If I had been told in a quiet chat it would have been sorted long ago I feel so embarrassed at what people must think of me, even my boyfriends friends have noticed apparently. I can't help but think this is partly my friends fault and I just know if I hadn't overheard them openly talking about it in front of me I still wouldn't know! The whole thing just makes me feel tired and sick of them all.

How do I get past this? The only thing getting me down is the anger I have that no-one told me. I've tried talking to them to get it off my chest but they just pass the blame around or say it was never a problem, which as much as I want to believe I don't think I can. How do I move past this?
