I am a single/married mother of 2 children, ages 1 and 3..my husband has been incarcerated for over a year.?

I cannot take much more of this. It seems like every time I try to do something I fail because I am so exhausted all of the time. I tried anti-depressants for 6+ months, but they just made me extremely lazy and in turn it just made me more frustrated. I have no support system...it's just me and the kids 24 hours a day. I tried them in daycare so that I could attend cles, but just getting them ready and taking them exhausted me. Then on top of that they stayed sick the whole time so I missed more school than I attended. I went back to online cles, but I have found that I cannot even do those anymore because I have no time. I feel so crazy and stuck and frustrated and like I am just dying...I have no health insurance..I am too tired to work. I have been feeling ill for a very long time, and it is really hard taking care of my kids like this. I have swollen lymph nodes all over my body and a large hard extremely tender lump below my right ribcage. Can this be from stress? I am trying to get some health istance..I have been working on it since June..our system is crazy. I am a nervous wreck...I guess I just need someone to help me. When I tell people how I feel they say it is just from the kids, but I really don't think so. I wish someone would just take me seriously and quit thinking that I am just depressed or whatever because I am not...I want to do a lot of things...I am so ready to work and get my life in order...My body just won't let me. I feel like I am making my kids suffer from keeping them home so much. I don't know what to do. I feel so stuck.
