The best advice I can give you is to just try to be confident when picking her up. Respect her, don't fear her. It may take some time for you both to get more comfortable with one another, and that's ok. Take your time, develop a trust with your snake.
They aren't capable of like, love, hate or any emotions like that. As has been said above, they tolerate being handled. They don't seek it out. You'll never see your snake looking through the glass of her enclosure wagging her tail excited to see you're home from work, school or wherever.
One trick that may help her acclimate to you may be to try wearing a t-shirt or something that belongs to your uncle. Your snake may recognize his smell and be more inclined to trust you. But, even with that being said, it's going to come to confidence on your part.
Don't give up, don't let it get you down. It may take a little time and effort on your part (your snake won't initiate it), but it'll be worth it.
Good luck! Hope this helped a little.
