First of all, I think that if you're spending that much money on weed, you probably shouldn't do other drugs. Stop coping so hard, you'll become a serious drug addict. I know that lifestyle is attractive but it's also shit and will set up you up to LDAR permanently.
Gotta disagree with most of what @theson says, largely because it's anecdotal evidence. My own experience was almost exactly opposite on all counts, which means that it is quite plausible that OP could be either more like you or more like me, and there is no way of knowing. I'll just start listing drugs and think of how well they fit your situation.
1. Benzos: I personally like them a lot because they kill my inhib, make me numb to the world. Similar effect to alcohol.
2. Alcohol: Good alternative to weed IMO. Not quite the same but cheaper, more accessible, and fun.
3. LSD/other hallucinogens: These give you a lot of energy at first and trip you the fuck out, usually putting you in a good mood if you have a good mental predisposition for them, but may also give you trouble sleeping and are more "hotboy" than other drugs (hard to stay normal in public and under scrutiny).
4. Cocaine: Good for quick pick-me-ups you can do throughout the day with little side-effects by bed time if you stop yourself.
5. Adderall XR/other ADHD medication that is long term: Great for productivity and putting you in a good mood. Take one in the morning, wears off by night for a fitful sleep. I've had good results mixing this with alcohol, this combination would probably be what you are looking for the various effects you described.
6. Opiates: Put you in a good mood, numb to the world, but don't last as long. Kind of similar to benzos but a more euphoric experience. Particularly recommend oxycodone for daily use over heroin snorting or others.
That's all I can think of right off the top of my head but if you have questions about any other specific ones, I can probably give you my take on it since I've done just about everything.
EDIT: Also take note that a lot of medications like the SSRI you took (anti-depressant) and some other drugs work best once you've acclimated to them, which takes weeks. Taking it just today might not even really do anything for you.
