Been there, done that, very frustrating isn't it?
You know you can probably get another e-mail account from one of the free places and use it at the public library? I assume (from your age and the children) that you have a car and don't live on campus so you are limited by money, not transportation. At least with a Yahoo or Excite account you'd be able to see the pictures.
I noticed you posted 3 things really quick, and figured you were feeling overwhelmed. Getting rid of a boyfriend is a big change, plus then all the weight issues and school and kids on top of that. Dang! It's a ton of stuff. Anybody would freak.
Does your school not have a counselor? My last 2 colleges did, though I didn't use the service. I don't know if it was primarily for trauma (eg. rape counselling) but they might be able to refer you some place if they don't do it. For years when I was in Boston, I had free care through Mass General Hospital because my income was so low. I was single and putting myself through college, I think the cut-off was $16K. They covered group therapy for me for free. You might qualify for some kind of assistance at a local hospital too. Lots of great people here, but you might find out you need something you just can't get online, so check it out for later.
Promised a friend I'd call her 10 minutes ago, so I must run. I'm in and out of this board several times over the day, or you can e-mail me at firstname.lastname@example.org
, which I check pretty frequently.
