Lose weight before summer blues

Options
I guess this might be more of a complaint. I want for the first time in 3 years to lose weight before summer and feel more confident in a bathing suit. But the thing about living in Texas is that all year round it is summer. It's only the second week of March and my 2 best friends (who of course are skinny) are already getting ready and invited me to go to her lake house to swim and tan and such for spring break. But I'm not ready! I'm not done yet! So I keep getting discouraged because it is like no matter what I do I will always be the "fat friend" and it will take forever for me to be on their level.

The last time we went out we were at a bar and these guys completely ignored me. Then one of them said to the other (quite loud so others heard and looked), "Just ignore her, we don't do fat chicks." Even though I'm married and would never cheat on my husband, ouch! Just ouch! It's extremely depressing. So I'm in a rut and just can't pick myself up.

By the way my friends are completely amazing and support me and everything. It's not them at all.
