Rocco, we can't see you or hear you, so it's really hard to get too specific with help. This calls up the classic response, "Get a good teacher and take lessons." If you've got a teacher already, then discuss your concerns with he or she. (It's amazing how often a question will get asked here before asking the person best positioned to help you).
Now, for some concrete advice on reducing pressure, no matter what "method" of playing you're using. You already know that you can't just pull the horn away from your face. I tried that for decades and got nowhere because no one gave me tools to move me out of the compensation I was using to get by.
Whisper-quiet practice will help you gain control of your embouchure and reduce your reliance on pressure. Start on the middle-line G, playing as quietly as you possibly can. The tone may be rough and the note may start and stop as you try to control it, but DON'T add pressure to clean it up. Keep blowing the note for several minutes (breathing as needed, but taking full, complete breaths), trying to clean up the note with small adjustments to your embouchure and getting a feeling of playing with no stress. Do this as the very first thing each day. Try to remember that feeling of no stress.
After a week or two you'll be able to play that middle-line G whisper-quiet with tone that clears up within a few seconds of starting it. It will feel totally stress free. When you get to this point, then start doing a G-C-G-C slur, keeping it whisper-quiet and stress free. The next step is an arpeggio up to G on top the staff and back down, keeping it stress free and whisper-quiet. That top G will be just as easy as the middle-line G when you've gotten the stress out and you're controlling with your embouchure rather than pressure. With a few weeks of solid work (really just a few minutes daily) your should be able to arpeggiate up to your highest notes at whisper-quiet levels with no stress.
Ok, I'll risk extreme flames and give you one more concrete tip. If you're a "true" pressure player, then you may not pass the
pencil test. Can you put a #2 between your lips without using your teeth and hold it parrallel to the floor for 60-seconds, using just your normal playing embouchure? If you can't do that, then you've likely been using pressure to achieve your range rather than developing your embouchure. Many people (including me just a few years ago) can't hold the pencil for even a few seconds. If you can't hold the pencil at all, start with half a pencil and hold it as described for as long as you can, up to one minute. After you can hold half a pencil for one-minute, move to a whole pencil, doing the exercise three to four times per week. This exercise will awaken unused muscles and show you the feel of how your embouchure should work. Check

Good luck,
