Is it normal that i'm not sure who i am.

Just express yourself. Find a way to outlet your thoughts to the outside world. Even if no one falls to their knees and praises your achievements, at least they'll know that you're there. I feel like this sometimes too, but all you can do is keep being yourself and take some risks occasionally.

It's normal but not at the same time. I mean it's normal to have these thoughts, but at the same time you should think about seeing a therapist. That could really help like figure yourself out and make you happier.

The most scary thing in life is one day looking at yourself and realizing you aren't who you thought you were. It happens sooner or later.

I have and still feel that way to sometimes. I think what your doing is putting your insecurities onto others as in you think that they are thinking bad things about you, when there really not. I would say talk to someone who you feel that you can trust and open yourself up to release these feelings. These feelings and thoughts are toxic and don't belong in your body.

i think alot of people will underestimate and claim to understand what how you feel, adn i think thats the worst part of it. that whenever, if you ever, tell someone tehy always say, oh yeh i know what you mean, but in reality they dont. Obviously just going by what you say and not knowing who you are, no one can ever say tehy understand, so when people on here say yourl grow out of it, thats not necesarily true. it soudns to me like you shuld read some philosophy, adn turn your pesimism and cynicism into an attempt to answer teh questions you seem to ahve no answers to. thats why im doing a philosophy degree, obviously you dont ahve to do that, just read stuff in your own time. Theres only two things you can do, but difrent ways to react to those options.
You can either accept that you feel like this and continue being unhappy, or accept it and find a way of making happiness or contentment out of it. or teh second option is to seek help, although all yourl get then is so called professionals talking their pre-determined bullshit abotu how youre 'ill' and 'depressed' and will try to treat you with counsilling and or drugs.
i can genuenly say i understand you, and i sought help and it was all shit, the drugs they gave me made me psychotic, and teh recreational drugs made it worse. eventually i came to terms with who i am and just cant wait until teh afterlife because that can only be better...

I've had those feelings before but only as a side effect of being worried about something important to me.

You're normal, and I wish I could say that as time goes by you'll find yourself and these feelings will pass, but the truth is, they may or they may not. Mine never have.

I used to feel like this at one point in my life. But it was very brief and I think it will be the same for you.
