Struggling with sadness and anxiety today

Today has been a little difficult and I'm not sure why exactly. I believe some of it might be hormonal- so it will pass. I'm 25 and struggling with the "life plan" in terms of career etc. I'm applying to grad school in Jan but am really doing it to please my mom. It's hard for me to trust my own instincts about things. It's for social work and I think I really need to take care of my emotional baggage before I try to help anyone else on a professional level. Working on therapy right now. I'm talking a break from my boyfriend and I'm pretty lonely. It's been one week. Just wanted to vent a little. Thanks
