Every small step forward is a positive move, even if it's only a tiny one. It's like the saying "How do you eat an elephant? Only one mouthful at a time."
It's great that you are taking those small steps.
Perhaps you could break down the doctor's appointment thing into smaller steps also? Like for example:
Step 1) Look online for local doctor's surgeries/offices, and where they are.
Step 2) Look to see if they have a website and a list of doctors
Step 3) Write down the phone number of the one that appeals to you the most
Step 4) Have some pre-prepared answers for any questions they may ask when you first ring up. Some things might seem super easy, like your name and address, but it's amazing how many people don't really know their own phone number, or their emergency contact person's number - mainly because it's all 'speed dial' these days - so make sure you have those kinds of things written down in front of you, if need be.

Step 4) Make the phone call to make the appointment ........ etc
Anyway, you get the gist, yeah? Let me know how you go, if you like. Still be here. Still be thinking of you. Take care. You got this! xo
