Compliant with medications that have had you stable for years. Getting to the point where you even question your diagnosis, wonder if it's all in your head, think that everything will always be normal even without the medication.

Then you forget your medicine one night, maybe the night after too. Suddenly you're irritable as all hell, everything around you is blurry and your memory is fuzzy,  you want to cry all the time, your sleep is gone, appetite is unmanageable, maybe you want to hurt yourself and you can't even figure out why.

Then you look at your pill container and just sigh, realizing what happened and realizing you'll never be off medication and that you need it to maintain normalcy.

Its an all consuming disease at some points, but stability is possible, you just need to remember to be compliant with whatever treatment you have. BPD sucks.
