Yes, online therapy is effective. In fact for some people it is even more effective than in person session. Particularly for people who have strong protectors that keep them from wanting to show feelings in the presence of another human. Maybe it’s a social anxiety or a feeling that I’m “not allowed to cry in front of other’s,” or a sense that I have to “take care of other’s feelings.” As you sit in the comfort of your home you may find the social pressures are able to slightly ease allowing you access to more of your full experience of feelings. There is a way in which having a screen between you and me can open up a space for emotions to come forth easier. As well, I have found I can continue to be attuned to you and hold the therapeutic space in a similar way I hold the space for in person sessions. You will also have the comfort of your own belongings around you, which can create more relaxation.
However, with online therapy it is important you are mindful of your own environment. You will have to take control of going to a room that is away from others in your household. You may find you want to use headphones. You want to provide yourself with the privacy needed to be open and honest with yourself and me. You will want to find a space free from distractions, shut off your phone, be away from others, to honor your therapy time.
