Hey shels, first off take a deep breath and relax a bit. You know I'm here for you, whatever you need. Okay, so you've discovered something new, exciting and special about yourself. Think of it that way, in a positive way...it's not bad news, no tragedy....
Why do you feel the need to "tell" your friends and family all at once? Do they need to know? or should I say, do they need to know before you feel comfortable talking about it? Maybe just pick one person, someone your close to, someone who's supported you in the past....are you and your mom close? Do you have a strong relationship with her, have you confided in her in the past? If not her, than someone else. The point is, there's no need to put all this pressure and stress on yourself. You haven't done anything wrong. Discovering new things about ourselves should make us feel good, not scared and stressed. Yes, there may be people in your life who aren't comfortable with your new lifestyle....but who cares? Your job is to make you happy, to take care of you...not to keep everyone else happy.
Try to take some of the pressure off of yourself, you're heaping it on way too high and under that kind of load you will break. So, be kind to yourself, be gentle, be reassuring. You can't please everyone, realistically nobody can, so don't even try or think that you have to, it's just wasting your energy and happiness.
If you really feel like you need to get this out now or soon, just pick one or two people who have supported you through your life, who tend to "be there" for you when you need it. And don't make a big drama out of the telling, just keep it simple. In this day and age, something like being bi-sexual is not as big a deal as people once thought it was.
So, think about what I've said, take some time to be nice to yourself and discuss this new development in your life with someone who will be happy with you...don't go straight to the person that you know isn't going to like it, we tend to do that, and it never serves us well....I'd tell that person last.
Please check back and let me know how your doing okay?
take care and stay strong,
