"Why should I prefer online therapy?"
Online therapy is economically more feasible in comparison to face-to-face therapy.
Since the sessions are held over the internet at wherever you are, you have don't have to deal with transportation and/or parking problems in order to meet with your therapist.
Some people can be reluctant to go to a therapy center or don't want to be seen at a therapist's office. Online therapy takes care of this problem completely. In this system clients meet their therapists at their own environment.
Clients feel more comfortable at their home or office, as compared to an in-office environment.
Compared to face-to-face system it is more convenient to cancel sessions in online therapy, therefore probability of paying for the unattended sessions is very low.
There are no restrictions on time and place so sessions can be accessed from wherever the client or the therapist goes.
Illness is not a reason to postpone a session. Your therapist is with you even when you are sick.
Only therapy is suitable for single sessions.
