I think you may be over doing it. If you are suffering with Anxiety I would focus first and foremost on getting more sleep but with less supplements. If you put too much into the mixing pot you can spoil the stew. You'll also never find out what is working best for you.
As for the 5-HTP, yes at bedtime for a sleep aid and daytime for PAD/GAD but more important is that if you are going to take it to treat the anxiety then pick one or the other, not both. Not bed time and day time as this is taking too much IMHO. Anxiety and panic usually zoom you up pretty good so a little drowsy stuff wont hurt at all. In fact, I always found the calming affect of a good dose of 5-HTP throughout the day when having an attack to be a very nice feeling. Never had drowsy issues that made me feel like I needed a nap. I was too zoomed up from the attacks. If the 5-HTP makes you feel like you need to sleep then most likely the attack wasn't bad enough to warrant taking the 5-HTP.
In more cases than not a "less is better" approach to supplementation is best when trying to figure out what will help you the best.
Nothing works the same for every one but I'm seeing and reading about more and more positive response with less to no sides from people supplementing with 5-HTP vs anything else. It's all I use now if and when I have an issue. If I want a sleep aid at times I use some Melatonin or Valerian root and I save the 5-HTP for when I need it to help me with an attack.

BTW, since I learned about treating my attacks with 5-HTP and got them to stop I've been attack free now for months. No issues at all anymore and there has even been way more stress in my life recently than before which usually pushes people like us the other way. I how ever am getting better instead of worse. I truly believe in the effectiveness of this supplement to help and even treat PAD/GAD attacks and symptoms in people who suffer from it. It's a God send for me.

Thanks, I am have decided to start off small and move my way up. Vit D which is good for health anyways will be taken daily, and the 5-HTP. I am doing more research on SAMe, as this seems promising.
