I am so sorry that you are feeling so overwhelmed! It's really tough sometimes, and confusing as anything.

No one can really tell you how to get better - but congratulations on taking the first step by going to see a professional! If anyone that you saw there knows you and asks about why you were there - was it specifically a mental health place? If so, they were there for something too! And if not, then they have no idea what you were there for

I'm a huge advocate of routine and goals. Set yourself a daily routine (start by writing down what routine you already have). Take a look at what's missing from this routine. Are you taking care of yourself properly? Have you included time to take care of your body's health, and have you included time to relax and do something that you find (or used to find!) enjoyable? Do you have time included in your routine to do your house chores and errands?

Once you have your routine of what you DO already... then you can start by making out your ideal routine that includes everything.

Then start to pick one of those things and work on including it every day. Once you find that it's successfully included in your routine then add another one of them and try to get it in there all the time. If the first one doesn't work out (and really now, give yourself at least a few weeks to get it in there!) then switch and try a different one.
