Hi,
Sorry to hear you are feeling this way.
Like many phases in our life, university can have ups and downs. There is no need to feel ashamed of yourself just because you feel overwhelmed and dropped out as a result. Whether to resume your journey at university is a personal choice, but you can always discuss the matter with your family and friends.
Starting again and going back to the same environment that caused you stress take courage, but once you have taken a leap of faith, things may start getting easier -- If you decide to continue your study, make sure you are engaged in enjoyable things outside of your degree this time. Try joining in societies and clubs within the student union, talking to student support team and attending mental health workshops organized by university. All of these methods will help enhance your experience at the university and make you university life less stressful.
Hope you find this helpful. If you have any more questions, feel free to drop me a message.
Best of luck,
Sophia
