Bike or no bike?

So I was thinking, I am autistic with anxiety disorder, my coordination on my left of me is effected by it but should I get into riding some type of bike? This has been thought about for months since this year began, so I am planning to experiment with the plan at hand, sure yes my balance is off so perhaps an adult three wheeled bike would be better?

Laugh if you will, I do not mind, for here's a girl who once had many health problems before she was eighteen, who actually wants to do better now she has no holes in the heart or asthma tying her down... I cannot even swim so... I have to do something right?

if I can ride on the back of a motorbike with someone in front of me, then I surely can try to do something in order for me to ride a bike?

I'm lost for knowing what to do... maybe I should just quit the idea?
