It is common for people with anxio-depressive state to have an anxiolytic combined with their antidepressant. The combination is good since clonazepam have a long half-life which means it will be more suitable for your since it will take more time to decay in your body. You mom was on Valium ( diazepam ) which have an even longer half-life and it's also a benzodiazepine like clonazepam.
Good combination but just have to warn you that benzodiazepines are very addictive and once you are addicted the withdrawal can last for several months.
