Why do I have problems with breath when I lay down?

Why can't I breathe, or get a satisfying breath?

• This is lengthy. Three days ago I started having difficulty breathing. It felt like I was breathing in hot air, and breathing out hot air. I couldn't get a satisfying or refreshing breath. Then I started getting an anxiety attack because I couldn't breathe. I don't know if this is related to the fact that I stopped taking Wellbutrin cold turkey three weeks ago, and maybe the withdrawal effects are just now catching up. I went to Urgent Care today because I still couldn't breathe, and they said my O2 was 99%, I didn't have a fever, and my chest x-ray was clear, as well as my lung sounds. Obviously I'm getting enough oxygen. I do get light headed when I stand up... I have to stop, take a deep breath, hold on to something, and then walk again. I feel like I can breathe better when I lay down, as well as at night when the air is cool. I tried Maalox and it didn't help. I tried a breathing treatment with Albuterol, but it didn't help. I started taking the Wellbutrin again three days ago when I first started noticing the symptoms. Hopefully it will kick in again and relieve these problems. I'm scared I have something seriously wrong with me, like HIV or cancer, because I am extremely fatigued, zero energy, just don't feel good, and can't catch a breath. I don't have swollen nodes, not running a fever, don't have a cough... nothing! But I just can't breathe! Has anyone else experienced this, or does anyone have any ideas as to the cause of this? Thanks!!!
