Hi i'm a 28y/M and have been having gi problems for over ten years without seein a doc. I've been experiencing?

I've always had a high fat diet with steady mucusy diarrea but as of past 6 months ive been experiencing Black mixed in my stool and it tested pos. for blood about 2 1/2 months ago with an at home test. My health insurance in pending for 60-90 days and without it no doc. will give me endoscopy or colonoscopy. Emergency dept. took a catscan and bloodwork and seen nothing abnormal. I believe it may be a peptic ulcer but I have more symtoms that dont correspond with that diagnosis like swollen eyes, insomnia, dizzyness/ Blurred vision, and dramatic weight loss.(lost 30 lbs. in 2 1/2 months). I'm not sure if the weight loss is due to change in diet. I've been eating fruit, potatos, and rice and taking prilosec, and centrum vitamins. Though the black is clearing up I'm still feeling dizzy daily and I look sick. Has anyone had symtoms such as these? Or known anyone with these symtoms? I'm extreamly scared and was looking for any feedback on a possible diagnosis. Thank you for your time.
