Some Random Advice / Hope it helps
Often where you may live, i.e. country, city, or state may affect where the best places are for you to buy supplies. I don't think any one meant any offense by asking where you live it was just a question to get you pointed in the right direction. I have found that silkworms, if you can find them, are also a tasty feeder that wont escape from your hand too quickly when trying to hand feed OR, groan nobody call me out on this as cruel please!!!, you can remove the back jumping legs of the crickets if that's all you have access to locally. I attempt to stay away from the mealworms or superworms on younger chams as my vet told me too much chitan, the stuff that makes up their outer shell, can be difficult for some younger chams to digest in large quanteties so if you're at all unsure about your chams ability to take it down it's just better to stay away from it all together. So if silkworms, waxworms, or even Pheonix worms are unaccesable at this point -- (it is rare to find a pet store that carries silk or pheonix worms they are mostly online orders only but you might luck out with wax worms) -- then you could have to result to maiming your crickets for now to hand feed your cham.
As far as your cham being afraid of you she probably is right now. It's a completely natural reaction on their part. Their reptilian brain, as much as we love to say it can, can't really emotionally rationalize the fact that you care about her. However!!!! She can be taught through example to realize that you're not a threat AND even that you are an individual that supplies her with food and water (big positives in a pets brain

). If it is possiable and you don't have any cats or other hunting mamals in your house to contend with you might consider getting your cham out and putting on a house plant on ficus tree near you while you do every day activities like homework, paying bills, or surfing the net. Example: I keep a large ficus tree in my office so when I write letters and pay bills at night my dear Dr. Suess can get out and climb all over my office. Also, and this is a fun project, consider hanging some climbing rope or dried grape vine from your ceiling. I've draped some rope out of my office ficus. It goes up to the ceiling and is attached to in multiple places there and around the room. This gives your cham a really cool "jungle gym" effect for them to play on. Giving the opportunity to gain height around you, this will make your chameleon much more comfortable and less stressed, and, by giving them free reign to explore and walk around without feeling confined around you they will come to realize that you don't have a desire to "hunt them" and you don't see them (your chameleon) as prey.
If you do try this technique I would allow your cham to explore, under your watchful eye of course for an hour or two at a time without trying to interfere with her activities for the first few times. After you've let her out a couple of times and let her do her own thing on a "jungle gym" of your design or just a house plant try hand feeding her out of the cage. This will make coming to you more desireable. However, if she dosen't seem interested in the food avoid following her around with it and putting it in her face this could only stress her out. I was guilty of this early on, because I'm horriably impatient sometimes, and it never did any good. Just know she'll come around to eating out of your hand when she is ready and MOST chameleons can be taught to hand feed with time and patience.
I guess in conclusion to this LONG and WINDY post is the fact that I wish the best of luck to you.
And, chameleons take time. I think whats great about this forem is that the people here REALLY want to help you. Learn from
our mistakes. Most of us, myself included, have lost a cham to the evils of glass tanks because we just didn't know and "that's what the pet shop guy said". And, I'm sure you'll take everyones advice and get things fixed. But, all of us have fallen in love with these goofy little bug eyed buggers and while it is true they are not "petting pets." These wonderful lizards can make fantastic companions if given the right environment in which to grow.
Good luck and Keep us Posted.
