Oh, I am studying to become a nurse myself, and I know how hard it is to find time and energy for yourself when you're constantly taking care of others. The tips I tried to follow are:
Plan your meals and snacks in advance. Bring healthy food from home. Don't isolate yourself from colleagues and friends. Share your experiences and goals with them, and ask them to support you in your journey. They can help you stay motivated, and you can get professional help. In addition I used https://essays.edubirdie.com/nursing-assignment-help to reduce my academic load during this difficult time. Don't worry about what you're doing wrong or what you could have done better. Focus on your well-being and your achievements.
