Please help me I don't know how to cope!

All today until now I've felt fine, been drinking fine, eating fine, just a bit tired and hot (hot weather outside). Only an hour ago I was hungrily eating a (fresh, packaged and in-date) sausage roll. Then suddenly I've felt REALLY s* and weak and dizzy, like I'm going to v*, my stomach hurts a bit and I've had (sorry TMI) toilet rush, but it wasn't d*, but it burned and now my gas (sorry!) does too!

What's happening to me?! I don't need this! I really don't! Just now I felt something 'lumpy' come up my throat partly and stay there! My parents are away, my bf is busy and I have to drive to work tomorrow and survive work - I NEED to feel and be well for this! What if I'm not? What if I'm ill tonight and my parents aren't here for support?

Please help me!Edited by: amy08
