I Have Been Diagnosed With Major Depressive Disorder,ptsd, Have Moderate

I have been diagnosed with major depressive disorder,ptsd, have moderate anxiety ( not many panic attacks lately)!! For last 3 mo. since med changes. I have been on Prozac for nearly a year. Trying to convince myself with a little mind over matter and hoping my lifes turmoil would calm and settle soon, all families have major things happen in life and sometimes your handed a few and you put your head up, shoulders back and get thru it. Well I have been trying to not be over whelmed with my pain and admit that I needed inpatient care. My son was struggling and me with him and he went to a facility and was just readmitted 2days ago and will be switching to their residential once stablized so of coarse I have to make sure he is safe and we fix problem just for him to change over night into someone I don't know and had to do something tat I was never going to do twice. Family members have surgerys and a few funerals inbetween the holidays and oh ya, custody battle! You can't make this stuff up. Well I am also on Wilburton 5 wks . Have just maxed out on dosage for both. Added queriquil 50 mg. 1x pm for sleep. I battle from fatigue and try hard to do tasks without falling asleep but once I lay down even given over counter med x to make me slepy and many 1 x a wk I will sleep. I either think. Or cry or just suddenly become very wakeful, more than I've been all day and I do this ALOT. The only reason I haven't self harmed is BC I want to do right for my kids and when I'm in the moment I can't do it I get my plan and prepair but always stop BC I find a way to stop knowing it would be wrong to do to my kids it would impact their lives and who they are as individuals, so I stop and say for that fact I. Can carry the pain till I am no more and will be released then I cry inconsolably for hrs. I usually am at secluded place. But when I wasn't I woke my kids and couldn't. Stop and they witnessed my breakdown. I'm on meds that affect chemicals to treat depssion and have no side affects. But my mental health is only still in motion being pushed forward by things that make me want to go to sleep permanently. I do therapy and phsc dr ever mo. What gives, when can I stop treading these waters and just breathe?
