Remember that the fastest way through the pain is through it. Drinking sure does make us feel good for a little while but it has a rebound effect and prolongs our suffering.
Steer clear and fight the good fight. I know you can do it.
Who knows WTF your H is thinking. It's all speculation at this point. No sense in trying to make sense of it and obsessing.
Get in the gym and really push yourself. Try to lift 5 more pounds or spend an extra 10 minutes on the treadmill. You'll start to gain some much needed confidence.
Hang in there, it hurts now. Self growth usually hurts so take comfort in the fact you will come out of this stronger and wiser.
This isn't your life, just a small chapter. Keep going, it will get better. I promise.
