Η Μοναστηρίδου Παναγιώτα – Ειρήνη είναι Ψυχολόγος, Α.Π.Θ. |Ατομικές συνεδρίες ενηλίκων και εφήβων (δια ζώσης και online). Η ανάγκη για ψυχολογική υποστήριξη αποτελεί μια πράξη φροντίδας προς τον εαυτό μας και ένα πρώτο βήμα προς την προσωπική εξέλιξη. Με αυτή τη φιλοσοφία πορεύομαι και εγώ ως επαγγελματίας ψυχικής υγείας. Είναι ψυχολόγος, απόφοιτη του Τμήματος Ψυχολογίας του Αριστοτελείου Πανεπιστημίου Θεσσαλονίκης (Α.Π.Θ.), και προσφέρει ατομικές συνεδρίες ψυχοθεραπείας και συμβουλευτικής υποστήριξης σε ενήλικες και εφήβους, τόσο δια ζώσης στο γραφείο της επί της οδού Λέοντος Σοφού 10, στο κέντρο της Θεσσαλονίκης, όσο και μέσω διαδικτύου, για όσους προτιμούν ή χρειάζονται μια πιο ευέλικτη μορφή συνεργασίας. Η επαφή της με τον χώρο της ψυχικής υγείας ξεκίνησε ήδη από τα φοιτητικά της χρόνια. Πραγματοποίησε την πρακτική της άσκηση στο Ψυχιατρικό Νοσοκομείο Θεσσαλονίκης (Ψ.Ν.Θ.), όπου ήρθε σε επαφή με ανθρώπους που αντιμετώπιζαν διαφορετικά είδη ψυχικών δυσκολιών. Εκεί απέκτησε πολύτιμη εμπειρία στην υποστήριξη ατόμων με άγχος, καταθλιπτικά συμπτώματα, ψυχωσικές διαταραχές και διαταραχές προσωπικότητας, μαθαίνοντας να προσεγγίζει κάθε άνθρωπο με ενσυναίσθηση, σεβασμό και αποδοχή. Από φέτος συνεργάζεται με τον Παιδικό σταθμό - Νηπιαγωγείο ¨ΠΟΡΤΟΚΑΛΟΚΗΠΟΣ¨, στο Ωραιόκαστρο Θεσσαλονίκης, ως ψυχολόγος. Παράλληλα, έχει συμμετάσχει εθελοντικά σε δομές ψυχικής υγείας, αλλά και στη διαδικτυακή πλατφόρμα ψυχολογικής υποστήριξης «Μίλα μου», όπου πρόσφερε συμβουλευτική και συναισθηματική ενδυνάμωση σε άτομα που αναζητούσαν άμεση βοήθεια και έναν χώρο έκφρασης. Οι εμπειρίες αυτές την βοήθησαν να αναπτύξει μια πιο βαθιά κατανόηση των ανθρώπινων δυσκολιών και να ενισχύσει τη θεραπευτική της στάση. Αυτή την περίοδο βρίσκεται σε διαδικασία εξειδίκευσης στη Συστημική – Συνθετική Ψυχοθεραπεία, ένα πλαίσιο που μου επιτρέπει να βλέπει τον άνθρωπο ολιστικά, λαμβάνοντας υπόψη το ευρύτερο σύστημα στο οποίο ανήκει — τις σχέσεις, την οικογένεια, το περιβάλλον και τις προσωπικές του αξίες. Επίσης εξειδικεύεται στην Παιδική Ψυχολογία και Συμβουλευτική Γονέων Παράλληλα, παρακολουθεί συνεχώς σεμινάρια, επιμορφωτικά προγράμματα και επιστημονικά συνέδρια, προκειμένου να εμπλουτίζει τη γνώση και τα εργαλεία μου, ακολουθώντας τις σύγχρονες εξελίξεις στον χώρο της ψυχολογίας και της ψυχοθεραπείας. Στο πλαίσιο της συνεργασίας, επιδιώκει να δημιουργεί έναν ασφαλή, σταθερό και αποδοτικό χώρο, όπου μπορεί ο θεραπευόμενος να εκφραστεί ελεύθερα, χωρίς κριτική. Μέσα από τη διαδικασία της ψυχοθεραπείας, στόχος είναι να κατανοήσει βαθύτερα τον εαυτό του, να αναγνωρίσει τα μοτίβα που τον δυσκολεύουν και να αναπτύξει νέους, πιο λειτουργικούς τρόπους να σχετίζεται με τον εαυτό του και τους άλλους. Πιστεύει βαθιά ότι η αλλαγή ξεκινά μέσα από τη σύνδεση – τη σύνδεση με τον εαυτό του καθενός, αλλά και με έναν άλλον άνθρωπο που μπορεί να μας δει, να μας ακούσει και να μας στηρίξει με ειλικρίνεια. Η ψυχοθεραπεία δεν είναι απλώς μια διαδικασία αντιμετώπισης δυσκολιών· είναι μια πορεία αυτογνωσίας, ανάπτυξης και ουσιαστικής επανασύνδεσης με τον εαυτό.
