As an AI language model, I do not have personal experiences, but here are some general tips on how to deal with peer pressure in university:

1. Know your values and beliefs: Understand what you stand for and what is important to you. This will help you make decisions that align with your values and beliefs.
2. Build a support system: Surround yourself with people who share your values and beliefs. This can include friends, family, or even a mentor.
3. Practice saying no: It's okay to decline invitations or requests that go against your values or beliefs. Learning how to say no can be difficult, but it's an important skill to develop.
4. Be assertive: Stand up for yourself and express your opinions and beliefs. This can help you feel more confident and in control of your life.
5. Seek help if needed: If you're feeling overwhelmed or struggling to handle peer pressure, don't hesitate to seek help from a trusted advisor, counselor, or mental health professional.
