Is it too late to fix?

Is it too late to fix? I am a teenager who has been stuttering for as long as I remember. It has definitely had its ups and downs, but I was wondering if it's worth the effort of trying to fix at this stage. Just for more information, I have blocks very often, and I stutter off and on. Lately it has been worsening for some reason, and that has given me the idea to seek help from whoever I can get it from. If you think it is worth fixing does anyone have any ideas besides the stuff you would find on a google search of how to fix it. Thanks for reading and sorry for the depressing question!
