You NEED a break - as with any relationship, sometimes we just need a bit of "self-time" in order to regenerate and get us back to center.
Look for some RESPITE care for your daughter or what about a day for your daughter at an Adult Day Care facility - she may need a break too and you could take some time for yourself.
OR perhaps a friend that would come and stay with her for a day so you could get away for awhile - get hair done, go to a sports event - whatever.
You do not want resentments or feelings of discontent to rise and not be able to shake them - they fester and grow - you need an outlet, she may too -
Stay way from H.A.L.T. - hungry, angry, lonely, tired. Not good for one's mental stamina.
You are a valuable caregiver to your daughter but if you wear out for whatever reason - that's not helping her. Look for some local RESPITE help - either get her to a facility that offers this service OR find an appropriate individual to come in to care for her while you get a break.
