I'm not crazy for wanting to go back to school right?

I'm pregnant with baby #3 right now. When I was pregnant with #2 I decided to start online classes. I continued after having my daughter but when she was about 6 months old my anxiety got bad with my husband being deployed and us living overseas without family and my son going through some developmental delays so i decided to stop. I didnt intend to stop for so long but here i am 4 years later and looking to start again. But am I crazy for thinking about starting while pregnant again? I can do this right? I'm afraid I'll get some bad anxiety/depression about it again but unlike last time I think I'll he able to at least talk to someone if that starts happening.
