I am very happy that you are improving, even though they are slow progress, they are progress and that is good.
People may not behave in a good way with us, and it happens to all of us to a greater or lesser extent, we have to get away from people who are that negative.
Friends are always few, friends are people who are happy with our achievements, and who are there to help us in times of difficulties. And they are a hard treasure to find.
Don't worry about what will happen, after you don't have to use the medicines, you will be able, when you have overcome the situation, to survive without them.
Best wishes to you, I hope if you have any failure, and I hope it doesn't happen, but if it does happen, don't be depressed.
It is also something normal, that is not a reason for defeat, along the way, progress is made, other times you fall, the important thing is to get up and continue.
