Dear Nayelli,
Thank you for trusting me with your story. I know this situation must be very hard for you. But I have some questions for you:
Are you giving yourself enough time to rest and recover?
What makes you feel most stressed: your studies or your family’s situation?
Should you focus more on helping your mom now or on finishing your education first?
You feel lost sometimes, don't you? 
Please remember by taking care of yourself, you are also helping your mom.
Take care,
Juliet Club
