What's your major/desired field? Uni career services will help a ton if you want something specific to your skillset.
If you're doing something in business/management, you can try online career fairs and networking events. If you're in STEM, reddit helps a lot by posting specific advice to the field. Some people will share links to fellowships and other opportunities too.
If you've never worked before I recommend applying anywhere and working wherever takes you! You never know, it could be a good learning experience and help your resume too. Remember rejections for jobs usually have little to do with your value as a human being. Sometimes they need to interview outside candidates and end up hiring an internal person. Maybe needs changed at the last minute, or someone else just had more availability. Keep chugging along, good luck ♡
