You'd be fine on Normal. If you're good at UnderRail, you'd be fine on Hard. But that's not a very good build concept, and it's not well implemented. That character is going to give you a real hard time in places and unless you're looking for a challenge (and if so, then by all means have at it) you're going to get frustrated.
Bilocation, Enrage, Frighten, Mental Breakdown, and all your TM abilities aren't going to benefit from Psychosis, so you're paying extra psi cost on all your abilities so, what, your crappy Neural Overload can crit a little more often? Tranq would be probably 3-4 times as effective as Psychosis, just on the raw numbers, for your build concept.
Don't use Thought Control as your primary damage dealer. It's not strong in the first place, and it's useless against robots. If you absolutely must use TC as your primary psi nuke, then at least put some points into Throwing and pick up Grenadier so you can lob EMPs and HE grenades to your heart's content.
Your stats are a mess. Your feats are all wrong (Recklessness for a psi build? So you can just eat a lot more crits while you try to close, I assume - but if spear is for finishing off, you're not going to get enough use out of it to need a little more melee crit - just make a bunch of Focus Stim instead). It's not a good build. But Hard and easier is mechanically simple enough that you absolutely can succeed with bad builds, so if you want to make this character work, it will. Just barely.
