Please Help Rescue Luna my best friend: Your Help is Needed

My beautiful husky is experiencing medical issues. She is my best friend; she's my baby. For those that don't know her story, I rescued her from a local park where she was abandoned. I've had her since she was about 6 months old. We named her Luna because she's always howling. She is now 2 1/2 yrs old. Anyone that meets her would fall deeply in love. Luna has the bluest eyes that can speak through your heart and soul. She loves to talk back and loves to cuddle with you wherever you're sitting or lying down. Luna will zoom across my apartment and jump on the bed just to play with you.

For the past couple of weeks, Luna hasn't been herself. She's not eating on her own or using the bathroom regularly. She has also been vomiting. I have taken her to several vets n found out in the X-ray she may have something in her stomach, not sure if it's an object or a mass or something else.

Luna has filled an emptiness in my heart ever since my parents passed and my sons moved away. I was able to make her my ESA companion, aka Emotional Support Animal, due to my own issues. I've prayed over and over for this beautiful creature God blessed me with. I can't believe she was placed into our lives just to lose her. Please, please, any help would be greatly appreciated.
