Endlessness has really sound advice. I would take heed of that advice.
Psychedelics can be powerful modes of change, even when we haven't been taking them

I can't even count the amount of times I hadn't been taking psychedelics and had gotten subjective/perceptual changes throughout the day, sometimes random, been going on for years n years. I'll tell ya what's helped me above anything else - the things endlessness outlined, they're so incredibly important to having a balance. Staying active is huge, and if you're already 'active' ...then become moar active, it can help beyond anything else I've found. Being plumped up on psych meds should be a last ditch attempt when all other avenues of treatment/therapy have been exhausted I feel.
I know when I would be brewing caapi on the stove, or before I nom down some mushrooms, there's definitely subtle shifts in my interior/exterior realities, what's going on ..I'm not sure [this goes for any psychoactive substance really]. I think many on this forum experience this more or less.
Also, give this some time. Time really does heal things, but you have to take that step. Takes perseverance and internal fortitude to stick through things, no matter how they may seem, and continue living your life in light of these things. They're often not as serious as we interpret them to be. We often paint a different picture.
And marijuana can be a powerful boundary dissolver, especially mentally. I know for me if I smoke too much canna too quick.. that overall 'feeling' I get initially when coming up, it can go south quickly if i'm not prepared [set/setting, being mindful of those]. I can feel it in my arms, legs and body, it's like this entire feeling that comes over me. I know for me that after years of psychedelic use that the initial experience buildup of smoked cannabis has taken a much moar intense turn. I think many here have experienced this and still do, so I don't think you're alone there.
EDIT: Just wanted to note that I'm definitely not some exemplar of what I said above, I've had my own battles over the years with things not as related to this, though the things I said above [as endlessness said] still hold true to life/post psychedelics despite many of my personal shortcomings. I've never been that good at taking my own advice when it comes to some things
