Best Answer - Chosen by Asker: maybe your posture is a problem
.. try having your shoulders back and relaxed also before singing practice your scales like do. re . mi . fa. sol . la. ti . do going for low to high and high to low.
another tip yawn to hit a high note and do the motorboat with your lips with the musical notes from your guitar
you just need to relax your thorat so you wont have to gasp for air in the middle of the note
