<human>: I've [24 F] been attracted to my family's mechanic for more than 5 years. There is likely a pretty big age gap, but I'm not sure how old he is. Recently I've had to get work done-several times- because I have an old piece shit car, so I've been there every few weeks-months. I'm interested in getting to know him, but I don't want him to feel uncomfortable. I had an opportunity to have an actual conversation with him because he had to drive my car to listen to the noise it was making--I failed. Instead of being my usual suave self, I had to hide my hands because they were shaking violently. I thought I saw him smile at me when I came in that day-- I had gotten about a foot of hair cut off, so I looked nicer than usual-- but I looked away and silently had a panic attack.
Other details: My dad is planning on speaking with him and asking if he would call me to help me find a car, so I should be getting a phone call soon... I'm usually pretty good at flirting, but I think the fact that I could be sexually harassing him turns me into a nervous wreck. What should I do?

Can you condense the text into three sentences or less?
<bot>: I have a pathetic puppy dog-like crush on my mechanic, but don't know how to let him know I'm interested without setting myself up for rejection or making him feel uncomfortable. Pls hlp
