27 weeks 4 days feeling depressed

I dont know what's going on with me but it seems everyday gets harder for me. I wake up with no energy, emotional. I have so much on my mind. I feel alone when I'm not alone. I feel lost. Ughhh I'm a very strong person ive been through a lot but this seems have got me good but I dont know what it is. I probably don't even make sense. Has anyone else felt this way all of a sudden? What can I do?? HELP
