Should I attend the funeral of someone who helped me but whom I barely knew?

Over a month ago, I had a mental breakdown in my house. My parents called the cops, and they called the mental health place, and two therapists came out to talk to me. A man and a woman. The man talked to me the most. He was very compassionate and helpful and he got me a therapist fast. I went to the mental health place for something unrelated, and he came out to talk to me and see how I was doing. It made m happy. A few days ago, he passed away in a car accident. I did know him from school but I never really talked to him. I decided to post on his timeline after he passed, and said how much he touched my life within the short time I knew him. Yesterday I ran into his cousin at the store. I said hi, and he came up and gave me a hug, and said he was super happy to see me. After we parted ways, I messaged him, because we are friends on Facebook, and told him that if he ever needs to talk then im here for him. So last night i saw a post from him saying they are doing a service at the church today and everyone is invited. The thing is I hate funerals. I didn't know him well, and im afraid people will be like "why is he even here?" Also I just won't know what to say to his parents. Should I just suck it up and go?
