Hiya

and welcome.
I'm sorry that some of your friends reacted badly when you told them about your SI. It takes a lot of courage to "come out"... and then your find you have their reaction to deal with on top of your existing problems.
I haven't had anyone react too badly - well not friends anyway, only family members

It helped to emphasise that "I am just the same Laura that I was five minutes ago before I told you: you don't have to treat me any differently".
It's good that a couple of your friends are being supportive, that's very important. The ones who are pulling away - could it be that they simply don't feel up to talking about heavy stuff? Perhaps if you made it clear that you still value them as friends and aren't necessarily expecting them to handle all the difficult stuff. Being specific about how you'd like them to help you is good, too.
Some people find it helps to give out leaflets about SI - try Deb's site
http://www.selfharm.net for that.
Do the friends who have taken it well know the ones who haven't? Maybe they could have a word with them for you.
I do hope your friends come to terms with it and can remain your friends. Support is good to have.
Take care
Love Laura
