I love your determination but please go slow, it will all add up in the end. And if you fall down, get back up and keep on going. I would make an appointment with your PCP first to get a good check up and then you can talk with him/her about where to go next...............you physician should be able to help you get into therapy. If you need meds you need a MD to prescribe.
Just to reiterate, instead of focusing on doom, stay in the moment. Give yourself breathing space. Consider what matters to you. Establish a few manageable goals, then take small steps toward achieving them.
For a fresh perspective, get a good night's sleep.
Gentle Hugs to you and lots of good vibes coming your way.
