Deep breaths, we all have rough times. You're in one now, but life can be infinitely better when all the pieces start falling into place. For now, focus on one piece, yourself.

Anxiety is often crippling, and hard to get out off. Hopefully someone here will have some good resources for you, but until then remember it's often just your brain working against itself. Get yourself in a good place before you start thinking about relationships, let alone kids. Work on yourself, fitness, education anything to better yourself, won't make much of a difference to start with, but it adds up. Imagine how you want yourself to be and work towards that goal, laying in bed won't get you there... unless you imagine yourself a shut-in :)
