Freaking out. Pain with no explanation.

I've been dealing with this slight pain pressure in my lower stomach left side for awhile now. Almost 2 months. Went to the ER for excruciating pain and found out I had a UTI. Took antibiotics that didn't work. Took more and started bleeding like a period only really light. I usually have weird periods but this one was really light. Went to the er for more pain and they did a ct and said I had "non specific pelvic inflammation." More antibiotics. I also have some severe anxiety so I feel like I'm going to die every day when I wake up. Like something isn't being diagnosed right. Pain in left and right side and been spotting/bleeding for almost 2 weeks now. Anyone know what this could be. Help.
