My best friend betrayed me, what should I do?

The person I told everything to texted me today in Spanish saying “I’m sorry.” He’s suicidal and I thought the worst. I saw him at lunch and I was so happy to see him and I asked him what was wrong and why he was sorry. He told me lll have to go up to the counselors later and I asked “why is everything okay?” He told me he told them he was “worried for me.” My past on how I was. I’ve never felt so betrayed in my whole entire life. I don’t even know what to do right now. Help
