Job search frustration.....

I would be so happy if I could find me another job now. Its just so disappointing that I have applied to probably 300 jobs in the past 2 1/2-3 years and I am still at the job that I have been trying to leave ever since. It sucks so bad that I am still at the place I feel like I am trapped. The few chances I have had to talk to anyone about a job I feel like I get my hopes up just for them to get crushed. I talked to a guy yesterday about a job that sounds like it would be a pretty good job. I would make a little more than what I am making now and it is Monday-Friday and no weekends which is definitely one of the things I am looking for in a job. The guy I talked to said he would start calling people in for interviews starting next week and as much as I hate doing interviews, I hope that I am chosen to do one because it would be so awesome if I could get this job and be able to finally quit the job that I am at now which is what I have been wanting to do for a long while now. The hours for the job I hope I can interview for are between 9am and 6pm. I know it would be so nice to not have to worry about not having to be at work until 9am especially when currently I am waking up at 3:30 in the morning to get ready to go to work and I hate it so bad. I feel like I can barely get any sleep because I am not going to bed until late so I am only getting between 3 1/2-4 1/2 hours of sleep every night. I am ready for a change. The only thing that kind of scares me is the fact of me being pregnant I would hate to have to leave my job for 2 months after I would have just got started but I could really use a new job right now especially before this baby gets here. I'm just hoping everything works out this time and I will be able to get this job. I know that when I do get a new job I hope I like it because I would hate to be trapped at that place and spending 2-3 years trying to find another one. It is literally torture what I have been going through. Feeling trapped at a job that you hate to even wake up to go to everyday is not fun. I just want the torture to be over once and for all.
