First time seeking support

So this is my first time really seeking any kind of support like this.  I went through a battered women's support group several years ago when I left my abusive ex, but hadn't really considered a caregiver's support group until now.  My fiance has been encouraging me to join something like this, but this is the first time I have.  I'm hoping to get some tips for dealing with things, and some peace out of all this.
