Counselling/therapy?

Has anyone had counselling and found it useful?

I'm not really sure if it's for me and I can't imagine it helping my situation but I'm just curious if it has had any positive results on anyone?

I've had a really bad couple of years. Lost my Dad in January and 2 days after his funeral my brother who's on 35 was diagnosed with terminal advanced small bowel cancer that has pretty much spread to everywhere. I'm not really open to talking and I'm not sure if I'm into seeing a counsellor...😢
