Natural problems

I think my hair texture is changing. It feels less like 3c and more 30 - ish than it has before. Maybe it's because I've been making conditioners or because my hair is growing but it's weird. Maybe it's falling out cause I'm slowly falling apart since I'm stressed out about school. I'm not sure what's going on. I've never had a perm or a relaxer but for years I would straighten the mess out of it with hot irons and straighters. It's been six months since I've used any kind of heat on my hair and I'm debating on whether or not I should straighten it for grad night through graduation. Either way it's been weird.  My mom really wanted me to straighten it. My boyfriend thinks that it's my own choice but I know he prefers my natural hair. So yeah...I want to see what it looks like straightened but I also want to keep my streak going ...maybe I'll figure it out I have a whole week to deal with it. I am not my hair anyways. Well as long as it doesn't fall out of my head.
