hang in there and dnot decide on your hair just cause youre frustrated there are alot of options.
1st id dust trimm off the ends evry 3 months for a while until I got less knots, then you could trimm only when you need to. another thing that almost getsbrid of thos knots altogether is deep moisterizing conditioner treatments.
while you're using any of the options you can experiment with natural styles and find products that work for your hair if you want to wear it natural in all its curliness.
you got alot of good advice i ll add some more options
option 1: wig it
wear a wig while deciding what to do your hair would be resting you could co wash daily and test out the bone straght relaxer look w/o the commitment. from what you said IMO evrytime you had to get a touch up, or tried to stretch and deal with the 2 textures you might regret relaxing.
option 2: phonyponytail
slick your real hair back with gel and stuff then have your real pony protected under the phony.
option 3: braids
braid it and forget it except for moisturizing misting spray daily.
if you decide to relax or textyrize think it hrough 1st dont make an impulse decision out of frustration.
