Individual psychotherapy
A safe space to explore your emotions and thoughts with tools backed by science.
Gisell Acosta
Less noise in your head. More focus on what matters.
Clinical psychologist in San Lorenzo and online. Using ACT, a contextual therapy backed by science, I work with teenagers and adults in a space with no judgment.
You do not have to be in a crisis to want to feel better.

About me
Clinical psychologist with a focus on contextual therapies.
I am Gisell. I work with people who come in worn out from fighting their own mind: the one that races ahead to everything that could go wrong, the one that expects too much of you, the one that replays the same scene at three in the morning. My job is not to get you to stop feeling what you feel, but to stop it from deciding for you.
Every process is different, so you will not find a one-size-fits-all recipe here. What you will find is a place where what you feel makes sense, and tools I use because they are proven, not because they sound nice.
I see teenagers and adults at Centro Alas, in San Lorenzo, and by video call from wherever you are.

My approach
It is not about feeling less. It is about choosing better.
I work with ACT, Acceptance and Commitment Therapy: a contextual therapy backed by science. The goal is not to stop you from feeling what you feel, but to stop that from holding you back. It is built on three moves.
-
01 · Make room
Stop fighting what you feel
Trying to shake off anxiety, guilt or fear is exhausting, and it does not work. Here you learn to make room for them so you can keep going, instead of spending the whole day pushing them away.
-
02 · Step back
A thought is not an order
“I'm not cut out for this,” “this is going to go wrong.” You learn to look at those thoughts from the outside instead of obeying them without realizing it.
-
03 · Choose
Move toward what matters to you
We look at what truly matters to you and take concrete steps in that direction, even if fear comes along for the ride. You do not have to wait until you feel okay to start.
The evidence provides the method. I provide the space where you can be yourself.
Areas I work in
What I can help you with.
02
Teenagers
Support through a time of change: identity, relationships, study and decisions.
03
Anxiety and being hard on yourself
For when your mind will not turn the volume down: always bracing for what could go wrong, needing everything to come out perfect, the feeling that it is never enough.
I can help you…
- Stop fighting thoughts that will not go away.
- Set boundaries without feeling like you are failing.
- Make decisions without spending weeks going back and forth.
- Get through a big change without losing yourself along the way.

What starting a process with me looks like.
Three steps, no fuss. You take the first one; the rest we walk together.

01
Message me
All it takes is a WhatsApp message. Just message me, no need to explain anything yet: we will work out the day, the time and whether it is at the office or by video call.

First session
We meet and talk about what brings you here. It is a space with no judgment, at your own pace.
“You do not need to come in with a rehearsed speech: untangling things is part of my job, not yours.”
-
03
The process
We set concrete goals and keep reviewing them, session by session.
“Therapy is a dynamic process: you will learn new skills and find tools to put them to use.”
A glimpse into my world.
What I share every week on @psicogisellacosta.
What people say after taking the step.
I came looking for calm and found a space where I can be myself, with no judgment. Every session is a breath of fresh air for the soul.
The support our son received was transformative. He learned tools for managing his emotions that he still uses every day.
I always thought therapy was only for moments of crisis. Now I understand it is an investment in my daily wellbeing. I recommend this space with all my heart.
Frequently asked questions.
If your question is not here, message me: I answer personally.
How long is each session, and how often do we meet?
Each session lasts 50 minutes. At first we meet once a week and, as you make progress, we space the sessions out.
How much does a session cost?
A session costs Gs. 220.000 and is paid in advance, before each session. Once we have set a time, I will send you the bank transfer details.
Does what we talk about stay between us?
Yes. Everything we talk about stays between us, whether in the office or by video call. With teenagers, we make it clear from the start what is shared with the family and what is not.
How long does the process take?
It depends on what you bring and on the goals we set together: every process is unique, and no two are alike.
