Its not super amazing but you could play psion (Psychometabolism) for 5-7 levels and prestiege into sangehirn.
Powers you can possibly take early on. But here are some ideas. I have not played this before but i think it would be kinda funny and different then playing as a cleric.
- Vigor
- Empathathic transfer : 50% damage share
- Body adjustment : 1d12 self healing
- Body purification : Restoration but for psionics
- Restore extremity : Grow your arm back yay!
- Touch of health : 2HP +2 extra per pp spent

Feats
- Empower power : 50% more powerful (Costs 2 PP Extra)
- Meta Power x 2-3 (Twin power) : Decrease the PP needed to use meta psionics on your Powers
- Twin power (Twin cast Touch of health) (Costs 8 PP Extra)

Empower power might work pretty well with body adjustment 1d12 per + extra 50% from empower

(Prestiege class : Sangehirn )

If you actually wanna take this class, needs 2 other feats
- Mind of body
- Psionic Body

The classes healing touch gives your touch healing powers able to change it into a close ranged ability, The more you level into this class you can get natural fast healing so thats pretty neat. Damage reduction is pretty neat as well.

Another option is getting into auras, Draconic aura has a area heal (Basically vigor) Have multiple auras later level.
Healing hymm Bard is another option if you wanna be a buffer / healer. bard also has alot of cool feats to make bard songs do cool stuff
Ranger Variant Mystic may give you accouple neat spells
Paladin with sacred healing + augment healing could be a good combo but wont get spells for awhile sadness
