I am depression. The person I used to be is gone, there is no going back from this. I'm just sat In the hospital while my mum speaks to cahms, trying to hide my neck from all the other patients. I'm desperate to leave the hospital and get home but I know I'm gonna try again eventually. I've been on
Started seeing a therapist in April 2013 because my mum was worried about me. The therapist was in her mid 20's, and was pretty, so I felt a level of attraction to her, and told her a lot of things about me that I hadn't told anyone. I was in high school at the time, an all boys one, so she was basi

I feel like the anti-anxiety effects of this drug (Fluoxetine AKA Prozax), which have been good in a lot of ways, have caused me to lose a certain sense of 'urgency' or 'appropriate' anxiety towards things like academic deadlines etc. Things I really should be worrying about don't really make me anx

A brief summary: so I had major depression & severe for anxiety for about 1.5yrs, it was serious & I was at an all time low, hospital admissions, the lot. Doctors suspected it was drug induced (from MDMA), which I completely agree with, it was the time I spiralled down HARD, and also situati
I am on 20mg of fluoxetine and it’s stopping me from crying almost completely, I can occasionally squeeze out a tear or two and I’ve had one been breakdown when I was drunk but other than that the feelings build in my body and I feel worse and worse but it has nowhere to go. I’m also breaking out in
7 months ago, I took fluoxetine for a total of 14 days, after a period of mild depression. Although far from being perfectly stable, I was still an energetic, passionate, intelligent young man with big aspirations and a lot to live for. Those 14 pills changed all of that. After about a week on the m

I just needed to vent about my depression and my issues with society's stance on it somewhere. I thought these were supposed to be the best years of my life? I'm not ugly, and I like to think I'm funny and friendly, so why don't people like me? I'm always alone. Always, always, always. I've spent my
Chronic fatigue. I feel so so tired and weak all the time. Brain fog so bad it is even hard to read and comprehend stuff. Insomnia. I have to take strong sedatives to sleep. I feel like death after waking up. Developed bruxism in my sleep. Noticed it only after it fvcked up all my teeth and they s
Hi all, I unfortunately, went through a tough antidepressant withdrawal from Venlafaxine, and after finding out how common the issue was I decided to get started on creating an application to help.

*This is more of a rant than anything. I'm sorry for the formatting. I am on mobile and not really able to think clearly right now*   One month ago, I was put in a psych ward by my parents (I'm still a minor) during what was one of the worst depressive episodes I have ever had. I was physic
I am at the end of my rope right now, and I have nowhere else to go except jump. I wake up every morning wishing it would all stop, and it's my last thought before falling asleep. I am finishing up my PhD this year, but I don't have nearly the job prospects I was expecting. I am in a field as a m
*This is a super long post*, but before I started my AD I was looking for something detailed like this to see people's progressions on their meds. I had a hard time finding much, and this is why I decided to track my own progress and share after 6 weeks. Backstory: 26yr F, have had anxiety and mild
I take Venlafaxine. Just increased from 75 mg to 150 mg. I used to masturbate a lot. Not everyday...but most days. Now I have absolutely zero urge to. I’m talking to a girl now and she says that she’s a “freak” sexually. But I’m basically asexual now because of my meds. So of course.
Hi, Reddit, Over the past month, I have been weaning off of Venlafaxine, I was only on it for 3 months but it has been a debilitating experience that should be taken seriously!
