While I’m of the opinion that most people can benefit from some self-inspection (but not too much, since studies show that too much self-introspection is associated with depression, and may in fact be more accurately conceptualized as ruminating rather than introspecting), not everyone really needs therapy.
You probably DON’T need therapy if:
a) What you are doing to help your problems is working pretty reliably.
b) You can count on yourself to be able to get yourself to do what needs to be done.
c) You have easy access to great support from your friends and/or family.
d) You are able to eat well, sleep well, exercise well and enjoy good health.
e) You don’t avoid your problems and you don’t feel overwhelmed.
f) You feel generally satisfied with how your life is going and with your relationships.
You MAY need therapy or could greatly benefit from therapy if:
a) You are frequently concerned about a feeling or something you are doing or not doing.
b) Other people have expressed their concern about your emotions or behaviors.
c) Things have gotten worse for you.
d) You’re having trouble getting yourself to do the things that you need to do.
e) You’ve been getting emotional for reasons that don’t seem to match up.
f) You’ve been having crying spells for unexplained reasons, or you feel overwhelmed.
g) You suffered a trauma and you can’t stop thinking about it.
h) You are using substances to escape or numb out.
i) You feel disconnected from others and/or from your life.
j) You’ve been showing signs of stress lately, such as frequent illness, trouble sleeping, poor judgment, etc.
k) Your thinking feels foggy or distorted.
l) You always assume the worst.
m) You mentally beat yourself up.

o) You don’t care about things anymore as much as you used to.
p) You can’t stop taking responsibility for other people’s problems.
q) You feel helpless, overwhelmed or stuck.
r) You are avoiding tough situations or potential conflict.
s) You feel that you overreact to things.
