I have two comments for you. One is it sounds like you're burning yourself out. You really need to cut back - that much exercise, particularly if you aren't used to it, can actually be counter- productive. Your body never gets the necessary time to heal itself and rest and then you burn out. You set yourself up for injury, as well, which can really sideline you.
If you feel you absolutely must do something, do something lower key, like some soothing yoga, or just take a long walk. Give your body the chance it needs to repair and recover.
My second comment is that you can not compare yourself and your success to others. Everyone's body is different - what works for one, may not work for someone else. Even if you're in the same family. Progess may be slow - it's an unfortunate fact. Make sure your goals are realistic and long-term. Aim to get healthy overall and maintain that lifestyle; don't try to do it all at once and in one month. Aim to do the best and be the best you can be in a reasonable amount of time and continue along that path and you will see your goals come to pass. Good luck!!
