I'm sorry things are difficult for you right now.
I'm glad you are trying to get out and about and do things that are good for you and fulfil you.
I do agree with Blackpup that we unfortunately do just feel emotions that much more- the good and the bad. This is why it is so important to take extra care of ourselves - and it's by no means a selfish approach - it's a necessity!

Surround yourself with a good suport group, that can pick you up when the wheels start getting a bit wobbly.
