As tough as it is, sometimes that thing about change your playground & change your friends SO applies to family too!
I had to kick mine to the curb 20 years ago, and had I not, I wouldn't be here today!
I've found that people who are not conducive to my physical and emotional well-being simply don't deserve to take up space in my life anymore.
Again, it's not easy (especially when it comes to family), but it is doable!
