HelpSaveMyDyingBeardedDragon

I have a bearded dragon who is dying he has tail rot and he has way more problems and he slowly dying more each day. I am currently unemployed trying to find a job as fast as I can but it has not been easy, I can't afforded the vet bill to save him. And I am desperate because I don't want to lose him and I'm trying everything I can but I know I can't raise up the money and time to save him where he'll still be alive. He doesn't have that long and I know it and I'm so scared. Anything can help a dollar or five anything can help I'm begging because I just don't want to lose my best friend.
