no support

sorry in advance if this is poorly written, i am so tired and i don't have it in me to try. i'm 23 and was diagnosed a couple months ago after having symptoms for 3 years or more (which got significantly worse beginning of this year, to the point my job fired me in february. i'm still unemployed w/ no benefits). people have left me because of my fatigue/depression (my boyfriend of 4 years and my best friend of 8), so i'm even more hesitant to ask for help for fear of people abandoning me. my family knows about how bad i've been doing, but have never attempted to help or even check on me. they know i've just been diagnosed and they still don't seem to care. i live with my dad, whose very abusive and everytime i've asked for help with chores (i'm the only one who cleans), it ends in him screaming at me and saying he doesn't owe me anything since he lets me live under his roof without rent. i feel like i've been drowning for years and now i've lost the ability to feed myself, shower, or do much anything else. how am i supposed to survive like this? i want to kill myself, i don't what else to do.
