Good evening,
You have not mentioned your mother's age.
It would help to know where the bleed was. From the details you have mentioned I'd look for the left side of the brain, because the speech area is there, also left sided brain is responsible for the depressive cognition. Its what we call organic depression. You need to see a psychiatrist who can a) start the necessary medication b) teach you how to manage these symptoms c) help you watch for any warning signs.
Your mother might need lot of attention like a baby right now.
Hope your mother feels better.
I hope this helps.
Next Steps
contact a Psychiatrist who would start a medicine.
