converting to a religionšŸ™

Hi ladies! 
Instead of me telling you the complicated reasons and story, i'll just make it short. So, Im wanting to convert to a religion (im currently non-religion) however im wanting this because my father passed away earlier this year and i want to feel more communicated with him through religion. So what religion do you suggest and should i look more into it? 
Note: i attend a catholic school most of my life and my mum is a Buddhist however whatever my decision is, she'll support.
