I'm so sorry you lost a special thing! It obviously meant a lot to you and now you feel bereft without it. I do understand your loss - I'd feel the same if I lost my fossil or my metiorite ( both hugely precious to me). the only way to deal with loss is to have a period of mourning and move on. The universe works in mysterious ways - perhaps it had served its purpose with you and you are being shown that you do not need specific materials around you. It is out there in the world, and imagine the joy it will bring its next keeper. Try holding a small thanksgiving ritual thanking the universe for the thing you lost and asking for it to be protected on its journey. Ask for guidance for yourself. When you least expect it, something new will reveal itself to you and you will know when it does. In the meantime, test your inner strength. You can always try the astral plane to reconnect with your object and enjoy it there. I meet my long dead cat for cuddles and relaxation in the bed that I have in the astral plane. It brings me great comfort. Blessings xx

Your charm was probably meant to guide and comfort you through a specific phase of your life and losing it may be a sign to move on to the next phase. Take some time to meditate on the changes it is time for you to make (whether you really want to or not) and maybe focus your will into creating a new talisman for yourself to help you through your next phase according to your Will, instead of leaving things to chance.
