I finally got the courage to speak to my family about my struggles, I went to my first appointment last weekend and I got diagnosed with depression and the doctor prescribed me Zoloft.

It shocked me when he diagnosed me; I was frozen in my chair and not saying a word. Even tho I saw it coming and suspected it for a very long time, but it was shocking news! I thought I would be happy to finally getting a diagnose, for finally knowing the reasons behind my suffering, but I am not, my condition even got worse and I feel like I am losing my mind. Even controlling my emotions and pretending I am okay is impossible.

Anyway, I try to accept it every day, that I have a mental illness, and I was going to the pharmacy so I can get my medication but then...... my family made me questioning everything.

They can’t accept the fact that I need to take medication to feel better, they believe in natural remedies, they also don’t believe that it is an illness, as they think it is just a down phase because of COVID and for not being able to get a job, they have mistaken it for sadness and I made my best to let them understand but I failed. Quoting my sister, “everyone has depression” — that line gave me an attack and I couldn't sleep because of the pain.

They don’t trust the doctor diagnose and they told me to not get the medication I wouldn’t listen to them usually but when it comes to taking a medication, it is a very sensitive topic to me because my mom passed away because some doctors misdiagnosed her with an organic illness, so they gave medications that made her develop a more serious organic illness and that led to death. So they are telling me that this will happen to me, and I am now thinking of running away from getting the help I need because I feel scared.

They even telling me I got worse after I visited the doctor, yes it is true, but it is because I am not faking and pretending that I am ok anymore, I removed my mask, and yes I got worse because I was not ready to hear that I suffer, so I am thinking about my future and too many things, but I believe It is a normal reaction and I am trying to calm myself down, but they making me feel otherwise and make my panic is higher than ever.

They are also telling me I am thinking about it too much and it is illusion, not depression. They don’t believe the doctor at all because he diagnosed me from the first time; they told me maybe I think of things that are not true; they are telling me this is a phase and my mind is overacting, everyone has problems but they are living, I need to tough up and get out more, be active more, work, etc, but that is the problem that made me open up and go to the doctors, I can’t do all of this because of the fatigue. They want me to travel to change my mood when even getting out of bed feels like exercise, so imagine how I am feeling right now.

I am very confused and scared; I didn’t get the medication, and I decided to go to another doctor for a second opinion, so they can believe me, and so I can be more sure. But I already feel drained, it was hard for me to even open up the first time, and I don't know if I can do it again, I want to shut down and communicate with no one.

They want to do brain scans so they can know if I am depressed; they want to see if I have low serotonin, and they think brain scans can prove that.

Is this even possible? And is it possible for all depression cases? Does anyone go/went through a similar scenario?

I am sorry for writing all of this before asking my question, but I had to let my thoughts out somewhere.

Thank you <3
