I applaud you for coming this far. When I was transitioning, if I'd tried to do it out of braids, I'd have failed by the second month. So that you came this far is praiseworthy. I can understand how you feel giving up. I hate failing at something I start, but it isn't really failure as you've learned something about you and your hair, what doesn't work for you. If you still want to continue this journey and can find a braider who understands hair and who will care for your hair and trim a little as you go, then do so. But if you feel like natural hair just isn't for you and that you will eventually want to relax it after you chop of the relaxed hair, then get your touch up. There are still braid-outs and twist-outs which can give your straight hair a look of having a different texture when you tire of wearing it straight. But there are also role models like Supergirl that can inspire you to continue your journey wearing relaxed hair.
