I will speak only of the clinical and psychoeducational branch, they are the ones that I know and have seen or lived:

Suicide: In cases of severe depression, a risk is the suicide of the person, as professionals, we must pay special attention to this type of behavior and take security measures (such as letting the patient know about the situation or attending to schedules extraconsulta), these situations are extremely difficult to handle, of course a case in which a patient commits suicide, can affect your career, either in the legal part, or in the personal part, because you can get to blame and affect your self-concept for it.

Physical injuries: I have already been bitten by a child with Special Educational Needs during a behavioral intervention, I also worked in a clinic where children with serious behavioral disorders were treated, and a classmate a child hit her against a table, pulled her hair , very strong physical situations.

It can also happen with adults, but it is unusual.

Mismanagement of emotions: If you do not learn to leave what you see in the office, you can carry many things that you can not fix and stress, it is vital to learn how to disconnect from your patients, not to a degree where you only link to work, but to a degree where you can remember and feel the situation, but also live your life, I always say "remember 2% to plan sessions and others, 98% to live, and thus have energy for 100% of linking at the time of the session "

Problems of self-efficacy: Self-efficacy is the part of self-esteem where we value how capable we are in our activities, a psychologist (a) who does not have the desired results with his patients, can be affected his self-efficacy and feel bad about himself for underperformance , which can lead to a lot of self-criticism and associated psychological problems.

Harassment: There are some situations where patients become obsessed with their therapist, this can be very problematic, since they can follow you at home or make sexual advances during the session, the code of ethics completely forbids a therapist to allow these advances , so there are ways to reject the same suggestions and continue the therapy process or plan, the therapist should be changed.
