I believe that everyone can benefit from seeing a psychotherapist. There is no magic line that has to be crossed to be "worthy" of seeing one. You can see one for many different personal reasons - problems with home life, school, making decisions, financial stress, marital stress, depression/anxiety, etc, etc, etc. You said "things aren't quite right in my head" and you are feeling a little nudge to check things out here. I think that's a good first step and one that is pointing you in the direction to try it out and see if it helps. I don't believe investing time and money in to helping yourself is ever a waste.
