What drug to take with bupropion to help?

In addition to the buspirone, You might consider Viibryd which has one mechanism of action similar but not identical to buspirone, and another mechanism similar to other SSRI meds: "Vilazodone's mechanism of anti-depressant action enhances the release of serotonin across the brain's serotonergic pathways by inhibiting the serotonin transporter (similar to SSRIs) and by simultaneously stimulating serotonin (5-HT1A) receptors via partial agonism (similar to the anxiolytic drug buspirone)".

I would advise giving both the Viibryd 10 mg and 20 mg (if necessary) doses a fair trial period. In fact, if 20 mg of Viibryd does not produce and adequate response You could try an additional adjunctive medication such as atomoxetine or aripiprazole before going to 40 mg of Viibryd. 40 mg is very difficult to taper down from as the manufacturer does not supply a 30 mg dose (and Viibryd tablets can't be cut).

Take care for now and all the best.

Hello,
The only thing I’ve personally been prescribed is Wellbutrin with Zoloft.

Hi, Bbnurse!
There are many options including the SSRI's (Lexapro, Celexa, Zoloft, Prozac, etc.), the SNRI's (Pristiq, Effexor, Cymbalta, etc.), the tricyclics such as Elavil, and the atypicals like Remeron and Trintellix. The best one for you is the one that works most effectively for you and that may mean a little trial and error.
There is a slight risk of an interaction between these medications and Wellbutrin and it's a risk -vs- benefit situation that should be discussed with your prescribing doctor. You can use this link for the Interaction Checker:
