18 weeks and... stressed ...depressed ...frustrated..feeling discouraged

I feel like my whole life is crashing ...ever since I found out I was pregnant there's been one disappointment after the other ... so many bad things are happening and trust me I pray and pray and ask god to give me the strength but after all I'm only human and I don't know how much more I can take... if everything is like this now? What the hell am I gonna do when my bundle of joy comes into the world? I'm just extremely stressed and drained and In a fucked up way I just think this is how my life was intended to be... because I try so hard to be a good person and do what I have to do and I'm over it ... I don't know if I can do this, I don't want my child suffering due to all the fucked up things happening to me ...
