Every person I have met, and I have met many, who are taking anti-depressants for depression/anxiety are people who for whatever reason have circumstances in their life which are causing them this immense suffering. It can be relationship issues, physical health issues, personality issues, financial, lifestyle (ie, excessive drinking, eating, whoring, etc). The possibilities are endless.
This is extremely daunting for doctors to deal with and takes many therapy sessions and hard work from all involved. Many cases are nonstarters. The people refuse to look at or change the issues that are causing the problem. Much easier to just prescribe some pills and write it off as "chemical imbalance". Not nearly as much money in the therapy business. One hr of therapy = $200 or so, vs $400+ for ten min with psychiatrist who doles out expensive pills (USA prices approx). Winner, winner, chicken dinner! Happy pills = happy doctor = happy patient...maybe??
The side-effects of these medications(SSRIs) should not be minimized. Search the internet for long-term patient's stories of withdrawal...not fun to say the least. Any medication that makes people OK with their <deleted>ty life situation needs some serious questioning IMHO.
One thing is certain, meditation doesn't work effectively if you are taking pills that directly effect your mind and thought processes.
I think you are on the right path, seeking improvement without taking medications. Enjoy the sunshine, outdoors, healthy food. Try to focus on the present moment and remember that nothing is permanent. Including life. Make the most of every day.
