You don’t say if you have a meditation practice or group of people to practice with. I assume that you don’t have that. In a small town or a big city you need a refuge and that is what meditation gives you, for a few minutes and eventually all the time. But it can be hard work. It comes down to your commitment and willingness to face fear, depression and anger, to own them. Psychotherapy can be really helpful, along with meditation, as well. Even a local gov’t agency can offer free counseling services, depends on where you are. But since you are in a Buddhist forum, I assume that you have a commitment to practice. Caring for your mother might be a big teaching. She won’t be there forever, maybe let her know you’re there for her 100%.
