There are many different types of therapy than the one you experienced.

I am a psychology student and with the groups permission for which I interned was allowed to make observations in a group dynamic. The atmosphere of mutual support and understanding may be good for you since you did not feel rapport with your therapist. Expressing yourself in that environment may help you articulate what is hurtful for you, examine this, and form some ideas on a approach towards taking the steps which will improve the quality of your life.

One reason that you may have a bad fit with your therapist is that he may be solution focused as opposed to problem focused - there are debates amongst professionals on this. A problem focused approach feels that the client needs to be able to release (transference) the pain, shame, anger that a client feels in a safe environment with the therapist. The therapist has a positive regard for the client that lets them know that this is ok (and helps them understand the difference between release and acting out). This could be likened to cleaning a wound before attempting to dress it.
Solution focused can begin (in my opinion) in tandem with this or thereafter - but any attempts to go directly to behavior modification or cognitive approaches without examining psychoanalytical content is not as successful (according to the APA) as a stand alone treatment.
Because insurance is hesitant to pay for psychoanalysis, due to the lengthy duration of treatment, a therapist who has a psychodynamic approach is a good choice. That is a composite of therapies that is less long term and has a high success rate.

You expressed a hesitation with opening up to your particular therapist so finding the situation which allows you to experience your inner world and bring this forth in your communication within a therapeutic setting will be very important in your progress.

I hope that was not to much jargon - the main point is that therapy can make a lasting difference in a persons life. A good therapist will help facilitate your gradual building of skills and strengths, and help you form clarity which will give you balance and control over your life. You certainly are worth taking the time to explore this and find out which option is best suited for you.

Do not despair - you are 23, and that should be good news because you can transform your present and your future. Yes there are many people who are older and who suffer - there is no magic age, Erikson's life stages continue throughout our lives, it is a good suggestion to search on the net and read about Erikson's 8 stages of development as is taught in developmental psychology.

We continue to face difficulty and transitions in our lives but with a competent therapist you can begin the process of deconstructing what does not work and structuring a solid base of peace and possibility for yourself that will shape your future. I would not say this if I did not know first hand that it is true :>
