>>5937871As someone who has been drawing on and off with long breaks in between I have to say it's not that big of a deal. The first couple of days are going to suck, that's all.
To start with your only goal is to start to build momentum again. Figure out the minimum amount of practice you can do each day and commit to that for a week. It can be as little as 30 minutes or an hour every day. The point is that you start drawing every day again.
It can help to pick an excercise you're familiar with and have done with some modicum of success before as a form of reference point.
In my case my go to is constructing figures from imagination and drawing gestures from photos. Eventually you'll start to shake off the rust and get back into it.
