Unless you like burning a lot of energy without getting stronger, I'd recommend avoiding p90x.
What I'd suggest is try to get a coaching session. If you can't do that, look into the Starting Strength Online Coaching. If that doesn't work, film every single set you do from your first empty bar warmup to your working sets. Watch each set of film before doing your next lifting set and make corrections as you go. You can accomplish an awful lot this way. Keep posting form checks, we'll help as much as we can.
