Any enema experts around? Question!

Everytime I try and do an enema, (red bag, hanging) I end up with pain and bloating in the left lower abdomen. I puff up and have gas and tenderness. My guess is I never get the liquid past there, or I do it wrong. I'm hesitant to keep trying if it keeps hurting. So, if anyone knows what is going on, or if anyone believes it is NOT good to do them, please let me know. I've suffered with Depression on and off for the last 11 years, and I'm thinking maybe if I could get my bowels clean, it would make a big difference. Please help!
