Confused about starting a new relationship

I like someone and i think he likes me back. I feel a mess right now dealing with some stress and depression but he is happy and have a nice life, he doesn't know about what I'm going through. So I don't want to be in a relationship with him cause i don't want to ruin his life, i dont want to be some bad vibe for him, is that a justified thought?? Or maybe i should give this a chance? Help please im confused thanks!
