Struggling to find the right antidepressant

I’ve had a lot of trouble finding an antidepressant that works well for me. They seem to give me bad side effects like blurred vision and exhaustion. I’ve been on Prozac for 3 years. It still gave me side effects, but at the time helped my depression so much. It made me feel numb, which at the time I needed. Then helped with everything else in life once the depression was gone. But it doesn’t help much anymore and the more they raise the dose, the worse the effects. I’ve tried others with no success. I was put on only Wellbutrin and it gave me a wonderful amount of energy, but it all was used on extreme anxiety. I’ve read how Prozac and Wellbutrin is like a wonder drug combo for some people. I was so excited, but literally no help. The Prozac sucked all the energy, I’m exhausted, heightened anxiety from the Wellbutrin, and somewhat depressed again. I don’t know what to do - raise medicines more? Try Wellbutrin & anxiety meds (if they don’t interact)? I feel so lost with this.
