I don't think it's a good idea to tackle this problem directly, i.e. going toe to toe with your issues. I agree with
@Roma, it's better to work on yourself instead. Nevertheless, it's a huge achievement that you are aware of that bitterness and envy, other guys just become depressed and/or aggressive without really knowing why until they become tightly-wound bundles of despair, so kudos to you for your insight and your courage to admit these feelings to yourself. However, I don't think another person, for example a healer, can make your problem disappear, you might just as well go see a conventional therapist.
Magic-wise (and mind you, I'm speaking as a beginner in this field), I'd recommend doing some angel work, especially with your Holy Guardian Angel. Some of the Protocols in Damon Brand's "Magical Destiny", for example, are highly therapeutic, especially Protocol Four "Releasing Pain"; I wouldn't recommend the classic Abramelin operation in your situation, much too stressful and disruptive.
That's what I mean with the indirect approach - instead of battling with your jealousy head-on, you're aiming at becoming a happier human being all around, as naive as this may sound.
