Medical Marijuana

I don't know where else to ask lol this probably isn't the place but its kind of important. My mom has really bad depression, anxiety, knee pain, & she has a very hard time sleeping. I told her I read online that medical marijuana helped with all those problems.. My mom isn't really interested but I talked to my dad about it and he really thinks it could benefit her. The only problem is, we live in Texas.. Where obviously weed isn't legal. My question is if we travel to Colorado, have her see a doctor, get her medical marijuana card, and have her try the edibles , oils ,and things like that there.. Is there a way we can get her those things here?? Like online or something? Its really no problem to pack our things and move there as long as she gets better.. But were trying to avoid that since she has her job here & my dad won't really be able to find any jobs there. This is really important to me and I'd appreciate any help or advice. I just want my mom back to the happy, pain - free person she used to be. She's only 46, she can hardly get up from the couch, she sleeps all day, she cries a lot.. I hate to she her like this & will do anything to make sure she gets better. Thank you!!
