Anxiety and prednisone

Hi, I'm new to this site, I've recently been diagnosed with crohns (about 6 months ago) and I've been trying to taper off prednisone... I was having a hard time remembering to take my pentasa so my cramping/diarhea started again so my dr. just increased my prednisone again to 20mg, and told me to try harder to remember to take the pentasa. today is my first day on 20mg... i was taking 10 and I feel horrible.. I'm shaky and really anxious and am sweating profusely... my hearts beating fast, is this bc of the increase in my prednisone?? I didn't think it would make this big of a difference since its not that much and I used to be on 40mg and it never bothered me this bad...
should i call my doctor? what should i do... i have nobody to ask please somebody give me some advice.

I have a doctors appt on aug 21, so I'm supposed to wait until then and then talk to my doctor. I'm so tired of taking the prednisone, I'm ready to be off of it..it made me gain about 15 pounds and the pentasa is just so hard to remember to take. I work 2 jobs so i have really weird hours. (trying to save up money to get health insurance... i have to do the high risk pool bc i got diagnosed with crohns the wk i was about to apply for insurance bc i had been at my job 30 days and i was just starting to get insurance reimbursement.) i'm thinkin about discussing a different option.. maybe humira? i know that they have a financial assistance program. do you have any advice on something else i could change to? I know its ultimately up to my doctor, but i want to be educated on other options so i could at least discuss them with my dr on the 21st.
im just so stressed out about everything.. the health insurance, feeling bad.. and working all the time to pay for my dr. visits. nobody really understands so i have nobody to talk to it about it all and i feel like im gonna go crazy, i just want to be normal again, i just turned 21 and i cant do all the normal things i should be able to do.
ugh...

pred sucks for everything except helping the crohn's. i become a crazy girl when i'm on it my bones ache i can't sleep i gain weight, i shake, my heart races. avoid salt when on it, eat potassium. helps with the weight thing. humira is great but insurences hate to pay for it. The thing with crohn's (at least for me) things work for a while and then they stop. and then i'm back on pred. I call it pred the dred. What works for me is adequate rest. And eventhough you just turned 21, avoid alcohol. It sucks but i learned that the hard way. Southern Comfort thru me into a flare once. Have you tried entocort? ASk your doc about imuran. It takes like 3 months to work but it can help. As for the pentasa, i took when i was your age and i used to take 8 pills twice a day cause there was no way that i could remember to take it 4 times a day. i don;t recommend this cause i don't know exactly how that horse pill works but that's how i took it.
