Since i’ve got more time atm here is a more detailed response.
What do you find ‘mongy’ about the high? Do you have no energy to do anything and just want to laze about? If so then thats indica. The buds should be small, fat and dense as fuck (i’ve had some taht you could squeeze real hard between your fingers but they still wouldn’t compress lol). Try finding a more sativa dominant strain..
Having said that, 99% of what is on the market is hybrids anyway, so there will be both indica and sativa qualities.
Another important thing to point out is what barrett said, since most bud is just grown for commerical purposes and not for quality they probably don’t flush the nutrients out for as long as they should, thus you will be smoking shit like potassium, magnesium, sulfur etc. which will probably have some negative effects (haven’t looked this up but it may be worth a try).
Have you ever considered that you only get anxious on it because it is already pre determined in your mind? E.g you think “Argh i can only get skunk lets hope I don’t get para :/” ultimately meaning you get para as weed just exacerbates the mood you’re in.
Have you tried mixing up the way you take it? I find joints to be a real, chill clean high (This is pure though). Bongs mong you out as you tend to take massive rips. Pipes I find to be a nice balance in between.
