Need advice on gaining confidence while riding, proper practice methods and more

(To skip the long reading, please go down to "TL;DR")Hello!So it finally happened.Back in late summer last year, one day I woke up and said "I think I want to ride a motorcycle" which popped out of nowhere (or something to that effect — I don't quite remember what exactly triggered me, but I started to notice and acknowledge that riding is "cool"). Within the next couple of weeks, passed the written test and signed up for a riding course. I was all excited and worked up during the course until I started to feel scared when they put us on the wheels, although later on I became competent. At the end of the first road test (cones set up in an empty parking lot), I became unsure of my interest because of my mistakes — lost some points by going out of the lines and such — until they told me I passed. With all the excitement built up, I wanted to get a bike right away, but for some reason I held it off; and it was September (I live in Canada).After half a year of cooling off and hibernation, my inner biker woke up and was psyched to buy my first bike.Today I picked up my first bike. I should've taken some riding course again before buying the bike, but my non-biker SO gave me a short financial-advice / confidence-boosting speech that I could just skip the course. Amidst attempting to be reconciled with 7-month-old memories of how to ride, I unconsciously dropped the bike (luckily at rest) right out of the dealership. I panicked wondering how on earth I would get home on this thing, but I went around the parking lot at the dealership several times to ensure that I felt focused enough. My heart was still racing, but after thinking I somewhat got it down, I decided to head home. The senses were slowly coming back to me on the way home — about 12 km of straight roads with traffic lights and just a couple of turns (and there wasn't much traffic due to the virus precautions). I jolted a few times, resulting in tiny heart attacks, while changing gears and accelerating from rest, but I was able to follow all the rules and get home safely.When I got home, I lied down and couldn't stop thinking about what just happened and imagining what terrible things could happen the next time I'm out on the road.TL;DRI would love to be part of this community and enjoy riding, but I don't want fear and worries to consume my motivation to ride.I cannot wait to get back on the wheels once I'm off, but I'm also afraid of other cars and such.Is this common or am I just not a rider?Maybe I'm simply overwhelmed at the moment and somebody can virtual-slap me across the face and tell me to stop being a wuss.Please help me get out on the road with more confidence and less worry!My initial thoughts are:• have safer safety gears on while riding• get collision and/or comprehensive insurance coverage on the bike• set up cones in an empty parking lot and practice different scenarios• choose less-traffic times to ride via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/fmvvbd/need_advice_on_gaining_confidence_while_riding/?utm_source=ifttt
