How do you make friends in Singapore?

Hey there everyone! I'm going to Singapore and Tokyo for one week next week. I'm going for a birthday holiday(19th) with family but I'm also looking to see if it's a place I'd want to live in the future or atleast go to university to in the future. I'm from the UK(18f), This is the 2nd time I'm visiting and I've fallen in love with the place however, I'm a little afraid of actually going and deciding this is where I want my future to be but being alone in a country I'm not very familiar with.

Any tips? I don't drink so things like pubs and clubs are out th window for me. However! I do love things like swimming, hiking, animals, anime, reading, extream water sports like jet skiing, ect. In short I'm pretty lively!
