Excessive bloating, gas, change in stools, malaise, lethargy

[PalmLeaves]

Hello, 25 years, female here.
It started in September of 2015. I actually noticed the start of some symptoms right around the time I got pregnant (ended up having an abortion later, I don't think it has anything to do with my illness though.)
The first thing I noticed was increased gas. I have struggled with gas in the past, and bloating too. But this just started becoming excessive. I noticed that I just have not been feeling good. Lately I just feel heavy and tired, achy, and in a way like I'm just poisoned somehow.
The bloating went from occasionally or after a big meal to every day. I find that eating makes things worse. I drink coffee daily in the morning but often go all day without eating until evening. I feel like I would probably have diarrhea or loose stools daily if not for taking activated charcoal. I have been taking it every day or 2 to firm up stools and prevent diarrhea. It has become a crutch.
Since September, I have lost about 10 lbs.
I often having gurgling insides, and get hiccups sometimes when bloated. Also (something I have always experienced) certain times what feels like a huge pressure on my chest is triggered from I have no idea what. My theory is that it's from not drinking enough water? I really can think of no reason as it tends to happen at random. I do drink water frequently because I feel bad if i go too long without drinking.

Anyway, back to the problem at hand, I recently felt what seems to be a lump (or 2, not sure if it's just 2 or just the same one that moved) right around/ beneath my navel area. I only feel it if i press down fairly hard. It felt like kind of like a potato. Not sure how to describe really. I even have an ultrasound picture of it. Not that anyone here could read that. It appeared as a black mass.
Since September of 2015, I have been noticing the following symptoms: gassiness, bloating, malaise, lethargy, and change in stools. I would probably have diarrhea every day or 2 if i did not take activated charcoal.
Symptoms have been worsening, especially the bloating. I cannot eat much without discomfort and have lost about 8 pounds since September. I often experience mild nausea, grumbling insides, stuff like that. Bloating every day and distended abdomen. Lately when I feel around navel area there is a lump or maybe 2; not sure if it was the same one that moved. I feel it when I press down very firmly. What could this be? I even saw it on an ultrasound and it looks like a big black mass.

I wonder if anyone has the same symptoms as me and may be able to shed some light on what's going on?  I need to go to the dr soon but actually have a huge fear of it.. Thanks
