Dude, your vas doc is an ars for telling you you are stuck with this for life, or anything like you speak of for life, especially if you have epididymis, which is treatable.
You are way too early to be making assumptions about long term disability, you will never get better, etc, etc.
You probably also experiencing some hormonal imbalance, which several of us have experienced ourselves in our early days.
Try to stay positive I know it’s beyond difficult, and your pissed, but it won’t help you, and will likely compound your suffering 10 fold. Been there, done that.
