I Need Some Relationship Advice

Sorry y'all, this is a long one. So I'm at college right now and I met this girl the first week here. We were filling in time slots for lessons and as I was typing my name in, she was typing her name in the exact same slot. So I finished first and then she then sent me an email with a meme, which I though was the funniest thing ever. So I respond with an email of a meme along with my phone number and she texts me a little later. So we've been going on dinner dates, studying together, and she even ran with me even though she hadn't ran in 3 years. Her love language is gifts, so I give her gifts that are meaningful. Then just the other day, we were studying and sitting next to each other and she puts her leg on mine. So I hesitantly put my hand on her leg. It seems as though things should be clear; it seems as though she clearly likes me and I clearly like her. But we haven't DTR'd and I'm overthinking way too much and doubting everything. Am I overbearing? Because I feel like I am. Also, how do I help her with her anxiety/panic attacks? I want the absolute best for her...
