To visit 94 yo mother in Texas

My name is Toni Joseph.  I just got a call from my sister in Lockhart, Texas and she informed me that my mother is worse off than I thought.  She is  94 and I've not seen her in a few years.  Right now I just can't afford the round trip ticket to go out there and it was suggested that I start this to try to get some help.  The best cost I could find is around $750 and I will end this when we get there.  Thank you for considering helping me with this
