I know exactly how you feel. I've been in a BSN program for about a year, right now I'm just doing prerequisites and courses that I can do ahead of time.
I've already had A&P and it was really tough for me.
Prior to entering this program I had done Medical Transcription for about 15 years.
I actually quit my transcription job last March so that I could just concentrate on courses. I also have 3 kids and I do my husbands billing for his company. My oldest is in college, freshman year so actually I have 2 at home, ages 12 and 13 !
It takes a lot of motivation but you will make it !!! Perserverance is the word I always hang on to!
Just keep telling yourself that you are smart enough and you will succeed.
Of course having a paying JOB would be great ! I've taken out loans and fortunately got some scholarship money. My perspective is the money is worth borrowing because it's for a goal and you'll be making so much more money down the road.
Hope this helps somehow, you can also e-mail me if you want to.
