It's really not bad. I had it done on a Thursday evening, and just relaxed the whole weekend. It was uncomfortable but not exactly painful. It felt like someone was tugging on your nuts for a few days.
Just do it. You don't need another human to take care of.
They'll do it, but they'll try to talk you out of it. I didn't need to do any convincing since my wife and I already had two kids, and we were both there at the consultation saying we don't want anymore. I was 25 at the time.
The doctor did say, "If you didn't already have two kids, I'd try to talk you out of this, but you both are here and don't want anymore kids". He said he's done if for someone as young as 21 with no kids before.
Yeah chances of any issues are pretty slim. Well worth the risk IMO.
