I can only really speak from my experience about meditation. Honestly, it's not easy for me. Sitting still and not letting my antsy mind and body convince me that I WILL die if I don't move, is often a losing battle. But, the more I practice, the better and easier it gets to discredit all my panic and 'to-do' lists. The brain is a muscle, it has to be worked and pushed to get stronger and more stable. It is such a fallacy to think we are just victims to our thoughts, that we have no say where the mind wanders or how we immediately respond to everyday things and even traumatic things that happen to us.
The biggest advice I can give is one I am constantly being reminded of by mentors and teachers: you CAN'T do it wrong. Don't go into this as another 'task' or something you suck at. Be a beginner at something, it's ok. No judgement, no guilt. Just practice being mindful. Aware of your present moment

Start simple: sit up nice and tall, but comfortably. Set a timer for 1-2 minutes. Notice your breath as it goes in, keep your focus on your inhale. Then, just notice your breath as it goes out, focus on your exhale. Your mind might try and wander, it's ok, just come back to noticing your breath going in, then out.
I use a lot of guided meditations and breathing exercises. The breath is always what brings me back to the present moment, so it's good to practice.
