First, want to start by saying you're a definite legend. You have achieved a massive amount in the past few years or so. Again, LEGEND!
I'll ask about something you may not have considered, you don't have to answer by the way (just something to give thought to). Do you see yourself as someone who copes with stress or do you see yourself as someone who constantly rises to challenges? The amount of challenges you've risen to would be enough to exhaust anyone. You definitely need to treat yourself to a 'This legend needs a break' holiday.
How often do you challenge yourself to rest or re-energise? Re-energising is probably one of the most important aspects of life. Running on empty can, without a doubt, impact mind, body and spirit. After all, how can we get a buzz out of life when the energy we need to feel the buzz is seriously depleted?
Crying...cry your eyes out but be careful because crying is another thing that can leave us feeling exhausted. Sounds weird perhaps but basically the body releases what it doesn't need (it cries, yawns, pees, poops, sighs and all the rest). If the crying is stress related, exhaust the stress as consciously as you can. Example: Instead of crying or sobbing the words 'I am hopeless', try crying the words 'This challenge is bl**dy massive!' You might even want to sob (as a follow up) 'and I haven't figured out yet how to rise to it without feeling completely exhausted'. 'Yet' implies you'll figure it out at some stage. You might decide to do some brain storming with friends, family or your partner. Challenge them to help you rise to the challenges you face. They might even suggest facing the challenge of dropping one to the jobs you're working.
It might pay to give serious consideration to a retreat of some kind. You know, one of those spas. Get family to fund it if they can. Anyone who realises how hard you've worked will want to fund what is basically a reward and a form of natural therapy (if they've got the cash). Gosh, even I feel like funding it. You deserve it. The thing about a retreat is - it's a way of re- treating your self to what you deserve in life: Peace, relaxation, a chance to re-energise, care, attention and so much more. If you've never treated yourself to such things...well...it's about time. You're special, you're an inspiration and you've been raising yourself in the most powerful and amazing ways.
Sigh, cry...let it out so you can make room for what you truly deserve - only the best.
