Fear of starting new medication

How do you guys get over your fear of starting a new medication? Currently my neuro wants me to start venlafaxine but unfortunately with every medication I’m put on I go on Google and read horror stories of people who gave it a shot. It’s gotten to the point where I feel like I don’t give certain medications a chance and I’m just saying they don’t work out of fear that they’ll give me scary side effects. Does anyone else deal with this?
