Yea, getting professional help can be difficult, especially if you don't feel comfortable with at least a few people knowing about it. I do encourage you to think about ways of getting help if it's what you want. But if it's something you really can't do at the moment, there are still many ways to help yourself. Having an honest think to yourself about the original issues that started all this, and maybe keeping a journal. Even better, if you feel comfortable, you can discuss them with a friend, even if they don't know about the SH, you can talk about the underlying issues. There are also many good self-help books and websites, this is one of them
So good to see you've at least found one way to reach out, even if it's a small thing.
I really hope you can find some support somewhere, even if it's just online and by thinking through things yourself.
