My heart is so heavy, I just can’t this 😭🥺

Please help. I’m having a major anxiety and I’m scared. I had symptoms like shortness of breath, mild chest pain, irregular heart heats and racing, sometimes blood pressure spikez, weakness, sweating, etc. I had ecg and ultrasound. Ecg showed possibility of arrhythmia, ultrasound results one mitral valve dysfunction. I asked the doctor if it’s serious he said not that serious and surgery isn’t recommended. He said I’ll need yearly checkup, also to take metroprolol 2 times ( but my bp is normal most of the time) and he advised me to see a psychologist for my anxiety. I honestly don’t know what to expect, if my life is at risk? Is this a serious diagnosis? Can I live a normal life? (Do Workout, physical activities, etc). I’m 38 and all alone, no family, no one, no support. I want to have family and kids. But after knowing this Isk just scared for my life. My heart is so heavy, please help me understand what to expect, if my life is at risk now? I just can’t 🥺🥺🥺😢😢😢😭😭😭😭
