Pooping terrifies me now

SW: 260 CW: 235 GW: 180

I know many people have talked about this, but I am having terrible constipation and I am trying everything!

I take fiber gummies and stool softener every day, I work out and drink plenty of water, I am eating high fiber foods. But now I am on day four of no poop. And every time I do poop it is a STRUGGLE and I am getting anxiety from it.

Any other tips? Or should I just go to doctor and hope they give me some better stuff to help?
