I think this poster has nailed it. OP, your post is full of dramatic highs and lows. Your sister has this
incredibly perfect life and you're jealous. And you feel
incredibly awful and are torturing yourself for feeling so jealous. In reality, you're just a normal person with normal feelings. Maybe if you'd be easier on yourself you would feel better both about yourself and your sister. Sounds like you need to work on establishing some psychological boundaries between yourself and the people in your life.
Again, as pps have recommended, talking to a therapist would be a good idea. Your post makes you sound like you feel trapped by your feelings with no way out but you'd be surprised how there may be an alternative way to look at your situation that you hadn't considered before that a therapist can help you see. I know that's what therapy did for me.
