Therapy is always tailored made to suit every individual's need. Every person brings his/her own uniqueness to therapy.
There's no hard and fast rule about who should seek therapy, every reason is valid.
For some, therapy might be a step to help them reduce the distress they feel, or get the support they need.
For others, it may be a process of self discovery, growth and validation of the emotions they go through.
Therapy is for anybody and everybody who wants it.
