You write you have been diagnosed with schizofrenia, though from what I know that is a pretty broad term - does it mean paranoia/delusions?
If you are actually suffering from something and need help, then you need help and I would advice you to get it.
If you are not suffering from anything, then you need to convince whoever (if anyone) is forcing medication upon you that you do not need it. Failing this, you need to get away and start a life of your own. Regardless, I would still advice you to finish college.
The way I see it, it is not impossible that there
is in fact an entity which is opposed to you. In fact, there can be many. Many unwillingly (or stupidly) create self-/destructive "patterns" which might be felt or even perceived. Further, every institution - every "name" - has an energy (including a purpose and possibly a will) of its' own.
As such, your family has an energy, your father has an energy and the psychiatric facility has an energy. When you stop taking your prescribed medication there is a good chance that the entity you are feeling "up against" is actually a mental construct of your own based on
your perceptions and feelings about these energies.
Like I said, everyone has energies and throughout life most encounters a whole wide range of people - some will raise your energy level simply by being in their presence, some will soothe your hurts, some will give you valuable tools, some will attack you on sight, some will suck the energy from you, and some will literally tax you.
It is important not to oppose the negatives - this means it will be waiting for you as soon as you let down your guard and keeping your guard up forever will essentially kill you - you will no longer be living, but merely surviving.
The trick is to rise above it and not let it affect you. This can be easier said than done - especially if one is a creative thinker and
especially if one is sensitive because it can be hard not to get carried away. Luckily, this is an occult forum and so let me tell you there are rituals which you can easily learn and employ which cause you to be unaffected by various energetic filth sent your way whether by intent or not.
If you feel that external energies are attacking you, then I would advice you to use the Lesser Banishing Ritual of the Pentagram at least once a day. (It is essentially a way to program your brain to create around your body a sphere programmed to redirect harmful energy around it or to simply absorb it and convert it to raw, useful energy.)
There are many variations of this Ritual - I advice finding one that is as simple as possible or simply choosing the one that
feels right. Google it if you don't know what it is.
Just know that it is your mind that is at work and that it can accomplish anything. Eliminate all doubt and believe this so much you simply know it and casually accept it as truth.
Some generic advice regarding meds:
Never just stop taking your meds;
Never just start taking your meds;
Always adjust by decreasing/increasing dosage as per instructions.
Seriously; abrubtly starting or ending such psychiatric treatment can mess you up even if nothing is wrong with you in the first place.
All the best,
Charlesman.
