Hi welcome to HCM.... You are taking antianxiety drugs and antacid pill.... If you are prescribed any antidepressant drug than it can lead weight gain... I will not reccomend you to use anabolic steroid that you have written in history.... For weight loss you have to burn your calories ... Do daily regular exercises ... Daily one hour jogging , running will be beneficial. . Low fat diet taken ... Refined and non veg food restricted ... Fruits taken more .... Try to avoid stress and for acid reflux avoid heavy diet and head elevation while sleeping .... Take care Advise : consult physician ....
