Hi
You can vent here anytime. Sorry your support system is giving you a hard time. It's really a personal decision and we have to do what's best for us. Good luck with your decision.
Some stylists know what texlaxing is. You've put so much into your hair thus far and it seems like you have length and health. So, since you sound apprehensive about self-texlaxing, maybe you should find a stylist to do it for you this time around, and as you become more comfortable with the idea (practicing with DC's, etc.), then eventually do it on your own? I am in awe of ladies who self relax -- I could never ever do it.
If you're in Atlanta, along with the recs from the poster above, try Salon Balisi and DontSpeakDefeat and I think there are more recs in the Salon Review Forum.
Oh, if you're available, come to the meet-up on Saturday.
Take care.
