OP do not be discouraged, it is only as complicated as you make it. This is a good time of year to start. It is cool in the morning, if you ride at a reasonable pace, you will not be all sweaty by the time you get to work. On the way home it doesn't matter you can shower when you get home.

As someone said the most important thing is safety, ride predictably, be visible and signal or point where you are going.

Once you start you may enjoy it and then you will want to commute on days that are not perfect, then it can get complicated.
