Hey Lizela ,
I got my sober bike here , you might take a tumble or fall off when your learning, i did when i learned to cycle .
Even people with experience sometimes take a tumble , but it is worthwhile dusting yourself off , getting back on as soon as you can and carrying on with trying to learn how to cope with the up's and down's sober .
When i fell off my bike as a child i didn't give up or beat myself up i got back on and with practaice learned how to do it , like any skill .
Treat yourself and your body gently , get more support if you need it , try to draw the useful lessons from the experience and leave the un-useful stuff behind .
Bestwishes, M
