Urinary retention. Steps i should take.

Hello doctor, I am an 18-year-old female experiencing persistent urinary issues and general fatigue. I have difficulty passing urine, with occasional burning sensation. I have also had a past episode of acute urinary retention where I was unable to pass urine despite a full bladder, which required consultation with a urologist at that time. The issue improved temporarily with medication but has now recurred. Alongside this, I have been feeling constant fatigue, dizziness, low energy levels, and difficulty carrying out daily activities. Recent blood tests (October 2025) showed low iron levels and severe vitamin D deficiency. I am currently on psychiatric medications: Sertagress 100, Fordep Plus, and Arip MT 2, and I am unsure if these may be contributing to my symptoms. Given my history and current symptoms, I would appreciate your guidance on whether this could be a urinary tract issue, medication-related, or something else, and what investigations or next steps I should take.
