I would suggest you just come right out and say it. But sadly you can't add a goofy smiley emote to the end of your sentences in real life so you may want to beat around the bush a little first.
Practice saying to a friend first. I have both done and had this done with me. It's not perfect, but it gets you used to saying it aloud. It's important that the friend be someone you trust not to judge or criticize.
