You ask how to get better and I think you are well on your way. 1. You are able to name and recognize your emotional state, mental state and behaviors that you find bothersome. 2. You have already taken initiative by joining PsychC. There are so many resources to use here and people going though similar things. 3. You know what you want to do next - find a therapist/ therapy team/ specialist. Kudos!
Reading your story sounds very familiar to mine when I was in College. I was going on and off different meds for depression & anxiety while in school and became incredibly overwhelmed. You are very smart to recognize that you need continued help from a therapist. I suggest you set up some initial meet and greet appointments as soon as you can while you have the energy to do so. I find looking for one using the Psychology Today website is the most convent option.
One step at a time, you got this!
