This is a dilemma indeed! Posts in the middle of rooms are always a little difficult. It would be helpful to have pictures of all four walls to suggest the best layout. From what I can understand of your dilemma, I've attached a layout that may work based on your description. It features a defined entry. So when you walk through the front door, you will see a console table with a couple of ottomans stashed beneath. They can come in handy for extra seating. In front of the console are two arm chairs, followed by a modular sectional - they make up your main seating area. To the right of the kitchen door is a TV console. Behind the sofa is a bookcase and to the right is a round table with a couple of chairs for games, paper work or what have you. You don't mention any windows. Is this the case? If so, we'll want to make sure you've got adequate lighting and colors that will work with the limited light. Hope this helps!

Possibly replace cot with large built in reading nook. This would provide storage on sides and give the privacy curtain somewhere to be when open. Bring sofa area out in front of tv area. Then being the dining area where the sofa is open part of dining wall if needed. This will give you enough space to extend the kitchen to door and still have mud room of sorts where dining room currently is. Upstairs looks ok consider looking at ship bathroom design. It is far more efficient than conventional. You must still follow local codes though.

I think that you should increase you drawing room area and reduce the bedroom area if you place the bed on south east side it will be possible
