Depends.
Do you want to talk to people and find that you can't, or do you just want to go about your daily and not talk to anyone if you can help it?
If it's the latter, then that's quite normal. I know alot of dudes that I somehow made friends with who don't talk to anyone outside of when they get asked a question or need to ask one themselves, but all these cats are emotionally self sufficient loners.
Also do you just don't speak to people or are you annoyed to the point where you just want to go before they talk to you, hence the eye avoidance? Getting pissed off at humans in general is quite normal, that's why I walk around with stereo headphones 24/7 and block out the daily. Alot of the times I hate hearing people have conversations, I hate seeing people stand in the middle of sidewalks or in aisles, I hate hearing people brag about shyt on the street that should be personal (Was coming out the bank one day and overheard an idiot talking about buying 2 Kilos of coke..within minutes I knew who he planned on getting it from and from whom based off of nicknames and locations) but I think a large majority of that stems for me wanting to be back on my own again away from everyone that knows me or possibly in the wilderness or some shyt on some hermit tip.
