when it rains, it pours

So I have been extremely stressed out lately and trying to stay sober so I haven't been online much. I was watching tv and accidently caught a nasty rape scene which caught me way off guard. I have not been able to sleep since because the nightmares I am having are so bad. I keep getting flashbacks again too. My therapist thinks it is because I have not faced what has happened to me. I dont know if I am ready to go there though.
Also theres random things bothering me. I have been annoyed with people in general because my friends don't seem to care whether I am having problems or not. There is a guy that I have been kind of seeing which I know is so wrong. I haven't told anyone in my life at all about him. However, I think I might be pregnant. The thing is that we were safe, so I thought. Now I am second guessing everything. I won't freak out until I know for sure. If I am, this is going to seriously upset a lot of people and cause a lot more stress for me. If I am pregnant, I hope I can stay calm enough. I have already had a miscarriage a long time ago due to stress.
