Blessed but highly stressed

I am soooooooo super stressed. I have a new job and im trying to learn everything. My boss is trying to squeeze everything in my head before she retires and sometimes i feel overwhelmed. No. Im not going to complain to her, i have to do it here. Im an overthinker and i am constantly in my head about everything. My weight- my boyfriend orders out so much and im telling him i cant but i find myself so stressed that i eat with him smh. Im trying to look and be my best, i have to stop eating like that. Smh. I have anxiety alot too just because there is a trip coming up to california with my sister and cousin that i want to go on but im afraid of flying (5 hr flight for me). Its constantly on my mind because i dont want to regret not going. They have been traveling this summer and i have been missing everything due to my fear, smh. I need strategies to get better. Feel better. Be, better.
