help dr im desperate!! 29 year old with erectile dysfunction

In October of 2014, I was told i had low testosterone with a level of 480 at 7pm at night. The Dr said i needed to go on TRT as low testosterone can have long term side effects. I wasn't experiencing any symptoms at this time. However the Dr insisted i start testosterone injections immediately. So, after the first injection, the erectile dysfunction started. Over the next 4 months of these injections i suffered diarrhea, erectile dysfunction, gynecomastia, and short temper. I finally told the Dr i wanted to be done, and that my lifestyle was worst on Testosterone than before! He then prescribes me 30 days of tamoxifen citrate in order to come off of the testosterone late February 2015. By May, i was deeply depressed, lethargic-sat on the couch all day long, had chronic diarrhea, erectile dysfunction, no libido at all, i would eat two bites of my food and would be completely full, and would have to run to the bathroom due to diarrhea. In october 2015, i still didn't feel better, so i had my bloodwork drawn. my testosterone levels at 11am were at 448. The Dr prescribed me clomiphene citrate at 25mg daily and anastrazole at .25mg every 3 days. The arimidex seemed to help with erections but wore off after several days. Here i am, still with erection problems, no libido, and extremely depressed. The Drs don't know what else to do. Can someone help me? I don't want to go back on testosterone injections.

Thank You for any help.
