Wait until you have a monthly period. Then talk to me about feeling tired.

I jest. Sort of. Your first two paragraphs are apt descriptions for every woman's PMS symptoms regardless of age.

Your third paragraph is your self-doubt and low self esteem and frustration over your situation.

That fair weather friend you described is a jerk. Forget about him. We don't find out who our real friends are until we reach out to people for help. Their response speaks VOLUMES about their true feelings towards us. I can't tell you how to react to your fair weather friend. I can only tell you not to take his response personally. It's not about you. It's about him. He's a jerk. Forget about him and focus your energy on yourself.
