Striving College Student

I am a student striving to keep up in college, left and currently rejected by my biological parents, I have been raised by a woman with a good heart here in our province, but she's overly aged now and can't keep up with the farming she does for my school tuition fee, nor would i have the ability to obtain such high values to keep myself well sufficed for studying in college. I am now a 3rd year Respiratory Therapy student. I would really love to continue my studying as I am moderately good in it, but unfortunately I am not that good enough to apply for a Scholarship. Hoping to bring back the favor to the woman who raised me someday. Me and my guardian would really appreciate any help. God bless you all!
