In my opinion absolutely not. There are a lot of reasons to live and none that I can see in your list that make suicide viable.
Of course no one can answer that question for you.
This is how I see it. There are lots of opportunities in the world for people with poor memory or lack social skills, and there are many non drug treatments that can help you improve both.
The violent thinking, is just simply that. Thoughts... think of all the horror movies and disturbing books and tv shows. Lots of people think dark thoughts. Your thoughts are not always a true reflection of who you are, nor do they indicate you are a danger to anyone, unless you take action, they are just thoughts. The fact that you seem bothered by these thoughts is probably a good indicator that you actually don't want to act on them. But I am not a doctor...just my opinion. I would only be worried if the thoughts start manifesting into impulses.
Here is what I always suggest to everyone at first.
There are a lot of Physical health problems that can cause neurological and psychological symptoms. You could be having memory issues , anxiety, and unwanted thoughts causes by anything from Mold Exposure, Lyme Infection, Candida or Yeast in you gut, thyroid issues... I even read of a case of a women that was labeled with Catatonic psychosis. She ended up with a severe calcium deficiency and being treated with high doses of Injected Calcium she made a full recovery.
So get blood labs done. Thyroid, Lyme, a complete blood panel with potassium and all minerals and vitamins. If that goes nowhere get some of the other tests done like Lyme, Candida , etc... you can get Lyme from a mosquito bite , you don't have to be in an area that has tics.
Also look at your diet. Do you eat a lot if foods high in glutamate? Sugar? Carbs? Processed foods?
Anyway that is where I would start, get some blood work done, and look at what you are eating. You would be amazed at how many people with the symptoms you describe have an underlying Physical cause.
Is it weird if I say I want to kill people?
Do you really want to? Or are you just having violent fantasies? Do you feel like you are going to, or are you just having thoughts. Thoughts and Actions are 2 completely different things. These types of thoughts could very well fall into the "Pure O" label with people that have "OCD". The reason why I put those in quotes is because they are just labels doctors use to describe symptoms they do not understand, I personally think most Psychiatric labels are bull shit. No not in every case... but so many people have a simple imbalance in their body or an underlying physical illness. Justin Beiber is a perfect example. He was depressed, sick, and started looking very unhealthy. Everyone speculated he was using drugs. So his symptoms were ignores , The truth is he had Lyme Disease and a doctor finaly diagnosed him properly and now he is doing better.
