If you like the up feeling, look for something that is sativa dominant rather than indica dominant and simply look for strains with lower THC levels.
Since you are not in pain, I do not know if you are actually going to like the high CBD strains, which are mostly for pain. I am wondering if rather than actually triggering seizures as cannabis is now being used very successfully in children to treat seizures, whether the strong cannabis is triggering panic attacks. Panic attacks are somewhat common in people who are not use to some of the strong strains. I saw a high CBD sativa strain when I was looking for CBD strains, but since I wanted something for pain and for night, I went with an indica. I want to say that I ordered from Seedsman and am quite displeased with the service from them (still waiting for seeds and cannot get them to answer any e-mails). So, I would not recommend ordering from him.
As lower THC is one of the things you are looking for, (can't believe I am recommending this) you might want to look at auto flowering strains. They are in part, ruderalis, which is basically ditch weed. Breeders have crossed ruderalis with sativa and indica strains to achieve a plant that matures faster and requires no dark period to flower. This lowers both the quality and quantity, but this might be the best way if you do not want too much THC. These will also come in sativa and indica dominant strains. You get that up high from sativa dominant strains.
Or you might change how you intake the cannabis or different strains. Is the Sour Diesel the only one you have tried? Have you tried just smoking a hit or 2? Have you tried edibles, you can make those as strong or weak as you want? Maybe a mild cannabis tincture--something made with glycerin to be smoked in an e-cig would be better.
Where did you get the "skunk bud" seeds you now have? Do you know anything about the strain? I wouldreally recommend looking for seeds that meet your criteria as much as possible, which you really can do now. This growing is quite an adventure , but it does take time, knowledge, and does take a chunk of money to get started. If you want to grow, it is not too early to start thinking about getting a space (or spaces) set up. And really, rather than just using what you might have lying around (especially if they are bagseed), get seeds that will do for you what you want.
