I see at least three problems here.
1) It was only TWO DAYS ago that you shaved. That is not long enough for anyone to become accustomed to a significant change.
2) You are giving WAY TOO MUCH power to the things other people are saying.
3) You are joining their chorus, using words like "weird" and "uglier" about YOURSELF.
As Sir Harry wrote just above, "Do you like it?" -- it's even too soon for you to know for sure, but I suspect you do like it. And as 30 days pass you will like it more and more because the look will be "you" and you won't be surprised when you see yourself in a mirror. You will notice how much easier it is to go through each day without worrying about hair loss and how people are looking at your BALDING head and is it worse today than it was yesterday?
Do not give power to others to control how YOU feel. Seriously, don't they have more important things in THEIR LIVES to worry about than your current hairstyle?
Lastly, don't incorporate negative terms into your thinking ... weird, uglier, etc. If may be difficult to shift immediately to "I look GREAT" but you can at least move to "This is a much easier look for me to maintain." I'm confident that by 30 days you'll be thinking, "A shaved head looks so much better for me than thin, disappearing hair."
30 days. Commit to it. Commit to being supportive (of yourself) and having an open mind and positive thoughts. You don't have to defend your choice of hairstyle to anyone else.
Let go of the stress. Begin living the freedom of the "new" you. A look which is consistent. Timeless.
I didn't see you before you shaved, but your "newly shaved" avatar photo looks just fine. If I were to meet you on the street you'd just be another person in the crowd.
Lighten up. Relax. Take a deep breath. And commit to 30 days.
