A few suggestions.

First, if you have any sort of portable recording device you can safely leave outdoors for a few minutes (maybe even with someone watching it for you), record a couple minutes of your practice from there, and see how loud or potentially annoying it actually is.  It probably isn't nearly as loud as you think out there.

If that doesn't convince you, maybe consider buying a heavy mute.  That will make even the loudest of violins pretty darn quiet.  Or, if you are inclined at all towards such things, maybe get an electric violin.  When they aren't plugged into an amp, electrics are very quiet.

Next, try to play a little for family and friends when you can.  It doesn't have to be a lot, but the new piece you're trying, or if you feel something is working out better.  You may not consider it great entertainment for them right now, but let's face it.. Most of them have had some hobby or obsession or new cat/dog that didn't really interest you all that much.  But you politely listened and looked, and fair is fair.  Their turn.  The reason I suggest it is that it can help with getting over being maybe a bit too self-conscious about other people hearing you play.  Sure, it won't be perfect.  But if they want perfect, they can buy a ticket the next time a world class soloist is playing in your area.  (And most of them also say their playing isn't actually perfect.. LOL)

If your neighbors haven't complained already, I'd say there's a good chance they won't.  They might even actually kinda like what they hear of your playing, who knows?
