Help with a new phone

Hello everyone, I'm a 22 year old medicine student

I use my phone on daily basis for my studies and PDF and textbooks however my phone is becoming obsolete and i can't use well it crashes on regular basis and don't accept any new materials for studying i tried to work along side my studies and managed to get half the money for the phone i need but keeping studies and job is pretty exhausting as i must be in top shape as i deal with patients and i need to keep my focus

please any donation would be greatly appreciated and i know 250$ is much and i wouldn't ask for that much but the rules for the website is the number must exceed 250 so i had to insert that number if possible once i reach my target i will close the fundraising
