This post is not really about your bald head. To me it is very clear that you are in a depression.
I used to be depressed when I was 15, 16 or 17. I'm not sure when it started and it's not clear where it ended. For me your posts are very recognizable. I would like to give you all the advice that I can, but the problem is that it (escaping a depression) needs to come from within yourself. It is a long process.
Unfortunately it is really hard for me to give any advice about how to overcome depression, because I know that I, like you do now, had a very different mindset when I was depressed; like 180 degrees the opposite.
Nowadays I would say all these things like all the rest here says: "Stop worrying so much, get on with what really matters!" yada yada. But I know it will not come through. Because I did not even know what really mattered: I wish I did. I can not even think of how I was thinking back then: nowadays I cannot possibly understand how I used to think about life back then.
For me, my parents saved me really. One day my mother came to me, angrily yelling: "If you do not talk now, I will call a psychiatric institure right now!" Because of my depression I wasn't talking to my parents much that year, while living in the same house. I think it was the thing that I needed to hear. I was upset that I have let my mother down. She was really unhappy back then. When I think about it now, I can feel her pain. But I know, things are good now
I love her, she loves me yada yada
(Try to keep it happy here huh!) Also, I did not want to go to a psychiatric institute! So instantly I had two things that mattered to me: my mum's state of mind and my own fear an angriness of possibly going to a place like that. All of a sudden: I had real problems that were close to me, instead of all the thinking: "this world sucks, everybody sucks, I am a good person, why can't people see this??! Why don't I feel love? It must be because of everything and everyone!!"
So I tried and tried to talk more to my parents (it sounds easy, but it was so hard to restore the relationship), do things... luckily I have very good friends and they were still inviting me for parties and stuff. They never knew of a depression whatsoever. I never showed it, I made a lot of jokes etc. I was a fun guest, but I was doing it for them. It did not come from within me back then.
Anyway... this is not about me. The good thing of the 'threat' that my mother did to me, was that I realized that there was something that mattered: I felt like a complete jerk to have let my parents, especially my mother, down so much. She might have been even unhappier than I was at the time, just to see her son ignoring her like that.
So, think about it: your parents, your friends etc all want to see you happy. Do it for them. Fake it till you make it. Hang on. It will pay back. You write that your parents are in a financial struggle. It would be great if they see you smile, to forget the troubles they are having. A change of location can always be a good thing. You could try a two month vacation to the Caribbean where people are friendly and not that materialist. (Try to stop blaming the world for what is really your perception of it)
I was not nearly out of my depression when I started losing my hair. Great timing... but it turned out good. I used it in the process of becoming undepressed. Deal with your problems first and then come back asking whether you should keep on shaving your head of making cool flames out of your remaining hair
Well, I just hope this makes sense for you. Try not to wait for an event in your life that will magically change your mindset. You have to do it yourself. It will get over. It's not the evil world that makes you depressed, it's your hormones probably. They will fade. I hope. All I can say, you have to do it yourself. Nobody can give you advice on a web forum.
