I'm getting really frustrated by the injuries and pains I am accruing from beginner-level lifting. It just pisses me off that at 22 it seems like I can do nothing right when lifting with intensity while it seems like others lift with worse form than I do at my gym and continue like it's nothing.

Alright enough complaining. I have stepped into the world of mobility exercises, myofascial release, body mechanics, human anatomy, etc and... it just seems like too fucking much. Where do you even start? Any ideas on resources that let you wade into it? Is it a good idea to find somewhere online to post videos of my form or should I just bite the bullet and spend money on a personal trainer?
