Trich is a common and treatable thing. Not a have for a lifetime STD. It happens. Get treatment and move on from it. All things in life happen and we learn from them. You'll probably never decide to not use a condom again, right? So, look at life's set backs as learning tools. However, I have noticed on various forums, you post a lot of anxious questions. I do think it would help you to speak to someone about your mental health at this point. Especially if you have a history of depression and anxiety. good luck
Mom's answer can't be topped, but I'll just say, breakups are hard. Life will always be hard sometimes. But grief isn't the end of life, it does eventually temper. Patience.
