I really do try to be conscious with the way I move and my posture at all times, its just tough when I feel so restricted in my range of motion

So if i need to spend more time in the bottom of my squat, is it alright if i turn my feet out to reach my maximum depth? and maybe hold onto a pole or use a band for counter balance? I cannot even get to parallel with straight feet. 

As for my tight hip flexors, I do the couch stretch multiple times a day and before bed i smash the psoas and quads (super painful and tight) with the supernova. Should I add anything else here?
