Well beachlover, I'm glad you liked my reply and took it as constructive (lots of people think i'm too blunt or trying to be offensive, i'm not). What I think would help you a lot is if you take a second, and think back on what you've learned so far on this forum and in life! You know that you're a teenager and your life has been changing a lot. You're getting a lot more options in and exposure to the world, and you're learning about yourself and all the different "personalities," for lack of a better word, that you could be.

You also have learned here now (or maybe reminded yourself of the fact) that teenagers are growing still and are at the point in their lives where they start to question and find who they are. Some do it sooner than others and with more ease. Others struggle and have a hard time with it. I know for some, what makes it so hard is, believe it or not, their self awareness. I believe that this might be where you are having the biggest issue, along with your confidence as we already mentioned (again, that's normal for a growing mind).

To me, you are so self aware that it's actually inhibiting you from being who you are and becoming yourself. Being self aware is a great thing, but it takes time to master (and you'll never be perfect at it). You are aware that you don't know who you are, and you are aware that you mold yourself to fit your peers. Hopefully by now after reading some replies you are also aware that this is a fairly normal thing for every person because it's only human nature to try to fit in with the people you're around. Now, where I think you could improve a bit in your awareness is by expanding even more. You're doing great for someone your age by being aware of your personality changes and such, but with only that and not the whole picture included, you're really just inhibiting your growth. The key part you're missing is that you're a teenager and these changes are normal! As a teenager, you WILL try to fit in with different groups, and it really is part of growing up. That is what you are right now. You're a teenager discovering himself. I think if you try to look at things from that angle, you'll be a lot more at peace and just be able to go with the flow and trust yourself more. Accepting that you're a teenager and these things are normal will also give you more confidence going into social situations because you'll know "hey, I'm going to act different around different people, but that's only normal because it's who i am at this point in my life."

Sorry for the long, drawn out response with such a simple ending to it, but I wanted you to see my logic and reasoning behind my statement so you really could apply it to yourself and your life.

Cheers,
Matt
