I've been diagnosed with schizophrenia as well, and I've got a pretty good idea of how you may feel with that issue in doing... Pretty much anything. Sadly, it's still an issue I struggle with daily, though it's certainly gotten better over time as I learn to deal with it. Very slowly, very gradually, and still very frustrating.
I've been diagnosed with Schizophrenia
Would you clarify? What are your symptoms? Preferably from your point of view rather than what you've been told.
To not go into extreme detail, I have trouble doing stuff. Not being able to get up to feed myself and such. Being motivated, so to say.
You should try to go into more detail if you can. There is more than a single "type" of schizophrenia, and a fairly wide range of symptoms that aren't necessarily always present in a person. As far as help goes, all I can really offer is the same advice I give anyone with just about any type of mental health issue- seek a psychiatrist if you haven't already. If you've been diagnosed it was probably a psychiatrist that diagnosed it in the first place, but I really can't stress how important it is to see a professional on a regular basis, even if money or insurance is an issue. It should absolutely be your top priority, as well as the priority of your parents/guardian. The earlier you get help, the better you will be able to cope in the long term. Medication isn't the only way to cope, but I strongly believe it's the least destructive route: my father managed to find some semblance of normality through trial and error of different mental techniques to calm his mind and reign in his irrational thinking, though that took a good 40+ years and a multitude of ruined relationships, jobs, and likely enough mental anguish to crush the average person's soul.
Personally, I've found medication to make a very noticeable difference in the way I think, the way I feel, the way I communicate, listen, and engage with people. It's not perfect by any means, I'm still a very awkward and eccentric person, but it helps break down a few bricks in the indescribable fourth-dimensional-esque social barriers that always inhibit my behavior when dealing with people, regardless of whether it's face-to-face, on the phone, over the internet etc. It took me roughly 8 years to find the right combination of medications that actually helped, but some of those years were spent with psychiatrists that honestly just flat out sucked at their job. I would also recommend having a therapist as well, though medication is still top priority. It's important to engage and interact with your psychiatrist in the same way you would a therapist, you need to talk to them and ask questions, tell them how you feel, what bothers you etc. It's the only way for them to gauge what kind of state you're in, and the more information you can communicate to them the better, even if it's hard for you to really say what you want.
