I feel overmedicated and exhausted

Last week I began a proctitis flare up as I posted before. After seeing the colorectal surgeon, he recommended I saw my previous GI. I did. He prescribed 2 steroid enemas and another pentasa enema in the middle of the day. He even orderd my increase of Entocort to 9 mg. I see this to be too much esp. that it took me a long time to come down to 3mg w/o flaring. So, I take Entocort 3mg, Pentasa tablets 2g, Nexium 80, an anti-ulcer drug in addition to ensure, a multivitamin and claritine and my restricted diet. The improvement does not exceed 5 %. However, I feel very exhausted, have shortness of breath and need to sleep a lot. Thanks God that I have the summer vacation. Is there anything I can do to boost my energy?
Your replies are highly appreciated.

I'm taking I think 18 pills per day plus an enema nightly. Stinks but must be done. Is your iron low that can make you tired as can low vitamin d.

Sherbear46, thank you very much. I haven't had a CBC for more than 4 months but the last one was all normal and I don't think my iron level might have fallen down that rapidly. Still it could be a reason and I'll ask my GI for blood work the next time I see him.

Thank you very much, Sheri. I'm a Crohn's patient but my intestinal inflammation is at rest now (keep your fingers crossed). Yes, I' m considering staying at home until my body regains its energy but what for a vacation is this.

Christine, thank you very much. I tried in the morning to walk for 20 minutes as I was forced to run some errands. I'm listening to my body and staying in bed. Did the surgery make you get rid of it? I'm afraid surgery is not an option for me as a Crohnie. Hope you're now better after undergoing it.

Hi Quincy, I'm a CD patient as mentioned in the title of the post. I eat only chicken, white rice, potatoes( mashed or baked), bread, pasta, cheese (i'm not intolerant to cheese milk), tea w few drops of skimmed milk and ensure. I can't tolerate any veggies or fruits whatsoever. Fats are my real problem. I have been on this diet for more than a year and a half.
My proctitis flare ups are characterized by severe rectal pain, a stabbing knife and swelling of the rectum to the extent that I can't sit down or even sleep, tenesmus, diarrhea and nausea. My stool can be classified as 6 on a Bristol chart. I rarely do have bleeding and if I do the cause is my intestines. I have chronic. anal fissures, hemmies and skin tags. This is all as far as my proctitis symptoms are concerned.
