exhaustion guilt

I just feel like such a LOSER for being tired after doing basically nothing. I've gained sixteen pounds and haven't exercised AT ALL, because I'm so damn tired all the time. Now it's even worse; it's like...climb three stairs, need to lay down. Eat a sandwich, need to lay down. Take a shower, need to lay down. Hate this feeling and can't stop shaming myself for it. I hate seeing all these pregnant moms doing crossfit and shit. I've never felt so down on myself before...what's wrong with me? Why can't I be the one doing crossfit and having a little basketball bump?
