oh dingoroo, i feel for you both. i know it is so hard to see someone we love be so ill and feeling like we are helpless. but you've already proven yourself incorrect about feeling helpless cause you got your bf to go look at the clinic that may be able to help him.
my husband becqme seiously ill with paranoid schizophrenia at age 25. we had a small son,age 3, at the time. my husband has his PhD in clinical psycholgy. i can't tell you how devasted i was when he became ill...and he had so much to give to so many had he stayed well. i'm sharing this with you because i want you to know i do truly understand how helpless you felt when your bf got worse. i felt the same way with my wonderful husband.
later i was diagnosed with bipolar disorder. so i can also relate to how you are feeling and your personal needs too. yes you do need a rest. restore the body and the mind will follow. a brisk walk to clear your troubled mind, a good nap, etc. and you will be better capable to helping him if you have restored your own spirit. balance in our lives is the key tho i have to admit that can be a challenge even in the best of times.
you both need support systems and friends in your lives. that too can renew your spirits. i encourage you to do this for yourself.
having expressed all that i wish you both well. it sounds as tho there is a strong love between you and your bf. harvest strength from that love. and as for you personally, save some of that very love for youself to see you through this rough time. you will need it. be kind to yourself and forgiving too. what you are going thru takes a lot of mentlal energy and you will need to "refuel" to keep youself spiritually fit.
hugs to a special lady...
