Trying to find answers

At the moment I’m really confused it’s my friends dads funeral in 4 days time and I’m in the funeral car with them and I don’t know why. Is this normal? My friend also blocked me on Sunday again I don’t know why. I’ve tried asking him but he not responding he just saying he busy he busy I can’t even call him because he either doesn’t answer or rejects the call. If I push I’ll be blocked again. I’m not best of people to be around I’m very caring but I’m over caring. Sometimes I panic and think the worst and me and my friend sometimes argue I don’t understand why he wants me in the car with him. I’m trying to explore my behaviour patterns to try to correct it and it’s hard right now I’m tired and burnt out.
