What coping methods help with anxiety, fear and loneliness?

Since my last hospital visit I have been anxious, fearful and kinda lonely. I didn't experience anything different during hospitalization but I just can't shake these feelings off. I am the only child in my immediate family and I was diagnosed with sickle cell 6 months after birth. I am now 24. It is difficult to share with my family because they might understand but they don't fully get it. Please share any methods that have worked for you
